J Clin Gastroenterol 2009;43:374-81, PMID 19098685: 2 patients developed severe hepatocellular injury after >12 weeks of HCV-796. [Abstracts]\nMechanistic support: McCown MF et al. Antimicrob Agents Chemother 2008;52:1604-12. PMID 18285474, doi:10.1128/AAC.01317-07. In replicons, nucleosides at 10–15× EC50 cleared the replicon, whereas NNIs and protease inhibitors selected resistant colonies; adding a nucleoside reduced resistance to the other classes. In vitro only.\n\nCONCLUSION (≤250 words)\nObserved findings:\n- Polymerase inhibitors were in early clinical testing by end-2010. Every human endpoint was on-treatment viral decline over 10 days to 4 weeks.\n- Nucleoside/nucleotide inhibitors (R1626, RG7128) gave dose-dependent declines of up to about 3.7 log10 alone and about 5 log10 with PegIFN/RBV. No resistant variants were detected clinically, which is consistent with a high in-vitro resistance barrier.\n- Non-nucleoside inhibitors (VCH-759, HCV-796) gave about 2–2.5 log10 declines, with rapid emergence of resistance (VCH-759).\n- Toxicity ended or limited several agents: neutropenia with R1626, and hepatotoxicity leading to trial suspension with HCV-796.\n- INFORM-1 was the first published all-oral, interferon-free two-class combination. It gave a median day-14 decline of about 5 log10, including in prior null responders, with no serious drug-related AEs.\nInference: a nucleoside polymerase inhibitor combined with a protease inhibitor was a mechanistically plausible route to interferon-free therapy with a high resistance barrier. However, no published polymerase-containing regimen had measured SVR by the cutoff, and the one durable-outcome signal (R1626, week 72) points to relapse.\nExplicit unknowns: whether any interferon-free regimen yields SVR, and after how long; the optimal duration; the durability of suppression without resistance; and safety beyond 4 weeks for RG7128. Full texts were not read.\nNothing here is advice to any patient.",

Primary endpoint was day-14 RNA; no SVR.\n(2) R1626 monotherapy (PMID 18553458): 14 days, mean declines 0.32–3.7 log10, no resistance.\n(3) R1626 plus PegIFN±RBV for 4 weeks (PMID 18570306): mean −3.6 to −5.2 log10, no resistance, grade 4 neutropenia in 39–78%.\n(4) PMID 18821613 is a Hepatology 2008 letter titled \"High relapse rate seen at week 72 for patients treated with R1626 combination therapy\".\n(5) RG7128 (PMID 20942646): no resistance or S282T after 2 weeks of monotherapy or 4 weeks with standard of care.\n(6) VCH-759 (PMID 19446909): 10 days, −1.97 to −2.46 log10, with resistant variants emerging alongside rebound.\n(7) HCV-796 (PMID 19072827): trial suspended for abnormal liver tests. McCown 2008 (PMID 18285474) documents HCV-796 resistance selection in 14-day monotherapy.\nSo the magnitudes (\"up to about 5 log10\"), nucleoside-versus-non-nucleoside resistance, and absence of any established SVR all reproduce.\nCaveat, and the reason this is partial rather than confirmed: the claim says the only durable-outcome signal found was the R1626 relapse letter. But a cited source, Feldstein 2009 (PMID 19098685), reports 2 patients on HCV-796 plus PegIFN/RBV whose HCV RNA was undetectable more than 6 months after stopping treatment (after severe liver injury). That is anecdotal, confounded by PegIFN/RBV, and does not establish SVR. It is still a durable-outcome observation in the contribution's own sources, so the \"only\" wording is inexact. Also, the abstracts do not report a quantitative HCV-796 human RNA decline; that detail would come from full text I did not access.",

The main short-term decline, resistance and toxicity figures reproduce; reviewed is an appropriate evidence label. However, the categorical no-SVR claim is false, not merely outside project scope. Opened PMID 18821613 (October 2008; DOI 10.1002/hep.22593) and its primary-letter reproduction at https://www.natap.org/2008/HCV/100908_02.htm, including Table 1 image https://www.natap.org/2008/images/100908/End-1.gif. Week-72 SVR was 5/21 (24%), 17/32 (53%), 18/31 (58%) in the three R1626-containing arms and 10/20 (50%) in SOC. R1626 was given for four weeks followed by 44 weeks SOC; SVR meant RNA <15 IU/mL 24 weeks after treatment. These data do not establish interferon-free efficacy or a clear incremental benefit, but directly contradict 'no published polymerase-containing regimen had measured SVR'. Additionally, PMID 19098685 (2009), cited by the contribution itself, reports both HCV-796 hepatotoxicity cases had undetectable HCV RNA more than six months after stopping medication. That is case-level durability, not a controlled efficacy estimate, but refutes the claim that the R1626 letter was the only durable-outcome signal in these sources. A corrected synthesis must distinguish absent interferon-free SVR evidence from existing SVR observations in interferon-containing regimens.",

            "note": "Arbitration: the dispute is upheld. I independently retrieved and read all nine cited PubMed records via NCBI efetch (20951424, 20942646, 18553458, 18570306, 18821613, 19446909, 19072827, 19098685, 18285474). All print dates are before the cutoff. Short-term efficacy, resistance and toxicity figures largely reproduce, and reviewed is the correct evidence class. However, the central categorical assertion that no polymerase-containing regimen had measured SVR is contradicted by its own cited primary letter. I opened the October 2008 bibliographic record https://pubmed.ncbi.nlm.nih.gov/18821613/ and the letter reproduction https://www.natap.org/2008/HCV/100908_02.htm, and downloaded and visually inspected its original Table 1 https://www.natap.org/2008/images/100908/End-1.gif. Week-72 SVR24 (RNA <15 IU/mL) was 5/21=23.81%, 17/32=53.13%, 18/31=58.06% in the R1626 arms and 10/20=50% in SOC. Four weeks of experimental therapy were followed by 44 weeks of peginterferon/ribavirin. These are measured durable responses in polymerase-containing regimens, without establishing interferon-free efficacy or incremental benefit. The letter's relapse title cannot replace its actual endpoint results. Separately, the 2009 abstract PMID 19098685 reports undetectable HCV RNA more than six months after stopping medication in both HCV-796 injury cases: another durable observation, though uncontrolled and confounded by peginterferon/ribavirin. Therefore the claimed only durable signal also fails. Additional precision: the approximately 2-log HCV-796 result in PMID 19072827 is from chimeric mice, not a quantitative human decline in that abstract. This is a substantive false historical conclusion, not a scope exclusion. The existing corrective draft CL-29 addresses the principal error; do not infer absence of measured SVR from absence of interferon-free cure evidence.",

The detail field contains just a header, and the artifact T-28_synthesis.md is not retrievable through UAIN, so I have not audited the evidence matrix or the correction ledger.\n\nPegIFN/RBV:\n- Manns 2001 (PMID 11583749, Lancet): SVR24 genotype 1 (GT1) 42% in the higher-dose PegIFN arm; GT2/3 about 80% in every arm.\n- Fried 2002 (PMID 12324553): GT1 46%.\n- Hadziyannis 2004 (PMID 14996676): GT1 52% at 48 weeks with standard-dose ribavirin.\n- So \"GT1 naive 42–52%, GT2/3 about 80%\" holds.\n\nNonresponders:\n- Jensen REPEAT (PMID 19380853): arm SVRs of 16%, 7%, 14% and 9%.\n- Shiffman HALT-C lead-in (PMID 15057741): 18%.\n- Poynard EPIC3 (PMID 19208349): 14% in nonresponders.\n- So \"7–18%\" holds, taken as arm-level extremes.\n\nDurability: Swain 2010 (PMID 20637202, Gastroenterology, November 2010, before the cutoff) reports 99.1% of SVR patients with undetectable RNA over a mean 3.9 years. This comes from a follow-up cohort, not from the RCTs themselves, which the claim's wording allows.\n\nProtease inhibitors, treatment-naive:\n- PROVE1 (PMID 19403902): 61% (P=0.02) and 67% (P=0.002) vs 41%.\n- PROVE2 (PMID 19403903): T12PR24 69% (P=0.004) vs 46%. The other PROVE2 arms were not significant (T12PR12 60%, P=0.12), and the claim correctly leaves them out.\n- SPRINT-1 (PMID 20692693): 54%, 56%, 67% and 75%, all significant, vs 38%.\n- So \"54–75% in significant arms vs 38–46% controls\" is exact.\n\nProtease inhibitors, prior failures: PROVE3 (PMID 20375406) gives 51% and 53% vs 14%. Correct.\n\nNegative findings:\n- R1626 (PMID 18570306, plus the week-72 letter PMID 18821613): only week-4 RNA and a high relapse rate.\n- INFORM-1 (PMID 20951424): all-oral, 14-day RNA change only.\n- BMS-790052 NS5A (PMID 20410884): single-dose RNA decline.\n- Debio-025 (PMIDs 18302285, 19353740): 4-week RNA only.\n- miR-122 (PMID 19965718): chimpanzees.\n- IC41 vaccine (PMIDs 18471515, 19559112): T-cell and RNA responses only.\n- Nitazoxanide: Rossignol, Egypt, GT4 (PMIDs 19135998, 18616643): 23 to 28 per arm, SVR 17–79%.\n- So \"no durable cure; nitazoxanide only small single-country GT4 SVR data\" holds.\n\nMinor caveat, not a reason to dispute: standard IFN alfa + RBV also had phase-3 SVR evidence before PegIFN. \"Only approach\" is exact if IFN-based therapy is read as one category, which is how the task frames it.",

All are pre-2011. This is a partial reproduction of the claim, not a complete audit of all listed sources or the unavailable artifact. Reproduced: Manns GT1 42%, GT2/3 about 80%; Fried GT1 46%; Hadziyannis GT1 52%; Swain 99.1% over mean 3.9 years (cohort includes peginterferon monotherapy as well as combination); REPEAT 7/9/14/16%; HALT-C 18%; EPIC3 nonresponders 14%. PROVE1 61/67 vs41, PROVE2 significant triple arm69 vs46, SPRINT1 54/56/67/75 vs38, PROVE3 triple51/53 vs14 reproduce the PI ranges. Caveats prevent confirming the exact claim: (1) GT1 42–52% omits IDEAL (PMID19625712, Aug2009; n3070) with 39.8%,38.0%,40.9%; even standard doses give values below42. (2) HALT-C's18% is from a common-treatment retreatment lead-in, not a randomized comparison of retreatment regimens; separate it from randomized REPEAT7–16%. (3) Nitazoxanide monotherapy (PMID18616643, Sep2008) measured SVR24 in4/23, so the unqualified interferon-free negative requires qualification. This small study does not establish multi-year durability, but neither may its measured SVR24 be erased. Restrict the negative to interferon-free DAA combinations or explicitly distinguish SVR24 from long-term follow-up. (4) Literally 'only approach' is too strong: Fried's randomized conventional IFN/RBV and peginterferon-alone arms also measured SVR24; Swain includes166 peginterferon-alone recipients. Say best-established combination rather than only approach. These are claim/method limitations, not project-scope exclusions. No artifact is excluded.",

SVR24 was the primary endpoint in A1–A3. Swain 2010 (A4) showed that 99.1% of 1343 people with SVR stayed RNA-negative for a mean 3.9 years, which justified treating SVR24 as a proxy for durable cure *for interferon-based therapy*. Results by population:\n- Treatment-naive GT1: 42–52% SVR24 with 48 weeks.\n- GT2/3: about 80% SVR24, and 24 weeks was enough (A3).\n- Prior PegIFN/RBV nonresponders: 7–16% (A5).\n- Nonresponders with advanced fibrosis: 14–18% (A6, A7).\n- Relapsers did better than nonresponders (38% vs 14% in A7).\n\n**Most credible near-term improvement.** Adding an NS3/4A protease inhibitor to PegIFN/RBV for GT1. Four phase-2 RCTs measured SVR24 as the primary endpoint and compared against a concurrent PR48 control (B1–B4):\n- Treatment-naive: 38–46% SVR24 in the controls. Arms that beat control significantly reached 54–75%, and the best arm in each trial reached 67–75%.\n- Prior failures (PROVE3): 51–53% vs 14%.\n\nEach comparison is within a single trial, so no cross-trial inference is needed. Because the SVR24 endpoint is the same one validated as durable for interferon-based cure, these are measured off-treatment responses, not just suppression [inference: we assume SVR durability carries over to PI-containing regimens; there were no long-term PI follow-up data by 2010]. The limits:\n- The benefit depended on the interferon/ribavirin backbone. Arms without ribavirin did worse: T12P12 36%, T24P24 24%, and low-dose RBV gave 27% breakthrough.\n- Telaprevir alone quickly selected resistance (B5).\n- Harms were greater: rash and more discontinuations with telaprevir, anaemia and dysgeusia with boceprevir.\n- The evidence covered GT1 only and was phase 2. Phase-3 results had not been published in peer-reviewed journals by the cutoff.\n- For GT2/3, no PI data were reviewed that could change the ~80% baseline.\n\n**Longer-term hypotheses (no durable cure shown).**\n- Interferon-free DAA combinations: INFORM-1 (C2) showed about 5 log10 suppression over 13 days, including in null responders, but measured no SVR.\n- NS5A inhibition: a single dose only (D1), with fast resistance.\n- Cyclophilin inhibition: strong on-treatment declines (E1, E2), no SVR endpoint.\n- miR-122 antagonism: chimpanzees only (E5).\n- Therapeutic vaccines: immunogenic, but no clearance attributable to vaccination (F1, F2).\n- Polymerase inhibitors: the only durable endpoint (C1) was measured on an interferon backbone and showed no gain over SOC (24–58% vs 50%, small arms). High relapse was linked to R1626 being given for only 2–4 weeks and to neutropenia-driven interruptions.\n- Nitazoxanide is an outlier. It is the only host-targeting agent with a measured SVR, including without interferon (17.4%, E4). But the data come from two small single-country GT4 trials, and its mechanism was unclear, so this counts as low-maturity evidence, not a leading route [inference].\n\n**Why the ranking holds.** The ranking rests on evidence maturity: RCTs with SVR24 as the primary endpoint and concurrent controls come first, then short-term virology, then animal and immunogenicity data. It does not compare effect sizes across trials. IL28B (A8) was a known predictor of PR response by 2009, so baseline SVR rates in any trial depend on the host population mix [inference].\n\n**Bounded conclusion.** On evidence public by 2010-12-31, PegIFN/RBV was the only approach with phase-3, durability-supported cure (GT1 naive 42–52%, GT2/3 ~80%, prior nonresponders 7–18%). The strongest near-term improvement was telaprevir or boceprevir added to PegIFN/RBV in GT1, which raised SVR24 in phase-2 RCTs (naive: 54–75% in significant arms vs 38–46%; prior failures 51–53% vs 14%). Every interferon-free or non-PI novel route was still unproven for durable cure.\n\n## 3) Correction / uncertainty ledger\n- CL-25 (dispute upheld here): I use the full naive range of significant arms, 54–75%, not 61–75%. Resistance on monotherapy is stated for telaprevir only (Sarrazin 2007). I cite no boceprevir monotherapy resistance source.\n- CL-26: I do not claim that Gao 2010 was the \"only\" human NS5A evidence. I excluded the AASLD 2010 conference abstracts (1881, LB-8) because I could not retrieve their original dated content. I claim only that no reviewed primary report measured NS5A SVR.\n- CL-28: IC41 RNA responders are stated as 3 of **all 60 randomised patients**, not 3 of 60 IC41 recipients.\n- CL-29/33/34: R1626 week-72 SVR is given with all four arms and denominators, taken from the letter's Table 1 on natap.org (the publisher copy was not accessible). \"Only on-treatment\" is not applied to polymerase inhibitors as a class. HCV-796 longer-exposure and post-treatment anecdotes (PMID 19098685) were not re-opened by me and are not used.\n- CL-30/31: I do not state \"no host-targeting agent had interferon-free cure in a controlled trial\" (contradicted by E4). \"0 of 24 placebo\" is labelled on-treatment. The host-targeting list is \"reports reviewed\", not an exhaustive census.\n- Hadziyannis 2004 defines SVR as undetectable RNA \"during 12 to 24 weeks of follow-up\", so it is labelled differently from the strict SVR24 in the other trials.\n- Access limits: abstracts only for every source except the R1626 letter (natap transcription). Arm-level harms beyond the abstracts were not checked. Phase-3 PI trials (ADVANCE, SPRINT-2, RESPOND-2, REALIZE) were presented only as conference abstracts in late 2010 and were **excluded**, since later journal publication cannot supply historical results.\n- Swain 2010 durability covers PegIFN α-2a-based SVR only. Durability of PI-based SVR is an inference.\n- Swain 2010, HALT-C, EPIC3 and IL28B were not in T-22's contribution. I added them from my own search.",

I also checked IDEAL (19625712), which the contribution does not cite. I did not re-open the R1626 week-72 letter (18821613 / natap); its figures match those already reproduced in the CL-34 dispute. All the sources are dated before 2011-01-01.\n\nWhat reproduces exactly:\n- Baseline trials: Manns 54% (274/511), GT1 42% (145/348), GT2/3 about 80%. Fried 56/44/29%, GT1 46%. Hadziyannis 63% overall and 52% (46-58) in GT1, with 48 wk beating 24 wk by 11.2% and no difference between the 4 GT2/3 arms.\n- Durability and re-treatment: Swain 99.1% of 1343 over a mean 3.9 y. REPEAT 16/7/14/9% and 72 vs 48 wk 16% vs 8%. HALT-C 18%, 35% at wk 20, RBV reduction 21%→11%. EPIC3 22% overall, relapsers 38% vs nonresponders 14%, prior PegIFN/RBV 17%. Ge IL28B about twofold.\n- Protease-inhibitor trials: PROVE1 41% (31/75), 61% (48/79), 67% (53/79), 35% (6/17), AE discontinuation 21% vs 11%, breakthrough 7%. PROVE2 46% (38/82), 69% (56/81), 60% (49/82), 36% (28/78). PROVE3 14/51/53/24%, arms 115/113/111/114, rash 51% (severe 5%), discontinuation 15% vs 4%. SPRINT-1 38% (39/104), 54% (58/107), 56% (58/103), 67% (69/103), 75% (77/103), low-dose RBV breakthrough 16/59, anaemia 55% vs 34%, dysgeusia 27% vs 9%. Sarrazin: resistant variants replaced by wild type within 3-7 months.\n- R1626: arms 21/32/31/20, wk-4 undetectable 29/69/74% vs 5%, grade 4 neutropenia 48/78/39/10%.\n- INFORM-1: −3.7 to −5.2 log10; −5.1 in naive and −4.9 in null responders vs +0.1 on placebo; no SVR.\n- BMS-790052: −3.3 log10 at 24 h, variants by 144 h.\n- Debio-025: −3.6 log10; −4.61/−4.75 and −5.91/−5.89 log10; hyperbilirubinaemia at 1000 mg.\n- Nitazoxanide: 79% vs 50% (p=.023) and 61%; monotherapy 7/23 vs 0/24 on treatment, SVR 4/23 (17.4%).\n- Lanford: chimpanzees only. Klade: 3 RNA responders \"within all 60 patients\". Wedemeyer: \"did not prevent HCV-RNA relapse\".\nThe ranking is by evidence maturity and uses within-trial comparisons only. The corrections from CL-25, CL-26, CL-28, CL-30, CL-31 and CL-33/34 are carried over correctly, and SVR24 is kept separate from on-treatment suppression throughout.\n\nWhy partial and not confirmed (the work reproduces, but the claim is inexact):\n(1) The claim's \"GT1 treatment-naive 42–52%\" range for PegIFN/RBV phase-3 evidence leaves out IDEAL (McHutchison, NEJM 2009-08-06, PMID 19625712). IDEAL is the largest pre-cutoff phase-3 RCT, with 3070 naive GT1 patients on 48 weeks of weight-based RBV, and its SVR was 39.8%, 38.0% and 40.9%. It is in RC-4526 and underlies the believed CL-27 (\"about 40–52%\"). The lower bound of 42% also comes from Manns' arm that used flat 800 mg RBV. The range supported by the evidence is about 38–52%. This is the same incomplete-range defect the task's how_to_check warns about (CL-25).\n(2) \"No interferon-free ... approach had shown durable cure\" sits uneasily with E4 in the same contribution: nitazoxanide monotherapy, which is interferon-free, gave SVR in 4/23. The carve-out that follows (\"nitazoxanide had only small single-country GT4 SVR data\") partly fixes this. A precise wording would be \"no interferon-free direct-acting-antiviral regimen had a measured SVR\".\n(3) Minor: the 7–18% range for prior nonresponders takes its 18% from HALT-C, an uncontrolled lead-in, although the sentence introduces it as phase-3 randomized evidence.\nSuggested restatement: \"…GT1 treatment-naive about 38–52% (IDEAL 38–41%; Hadziyannis 52%)…; no interferon-free DAA regimen had measured SVR; nitazoxanide had small single-country GT4 SVR data including 4/23 without interferon.\" With that, I would confirm.",

Almost every figure in the evidence matrix matches its source.\n- Manns 2001 (11583749): 54% (274/511), GT1 42% (145/348), GT2/3 about 80%.\n- Fried 2002 (12324553): 56/44/29%, GT1 46%.\n- Hadziyannis 2004 (14996676): 63%, GT1 52% (46–58), +11.2% for 48 vs 24 weeks, GT2/3 no significant difference.\n- Swain 2010: 99.1% of 1343 over a mean 3.9 years.\n- REPEAT (19380853): 16/7/14/9%, and 16% vs 8% by duration.\n- HALT-C (15057741): 18%, 35% undetectable at week 20, ribavirin reduction 21%→11%.\n- EPIC3 (19208349): 22% overall, relapsers 38% vs nonresponders 14%, prior PegIFN/RBV failures 17%.\n- IL28B (19684573): about twofold effect.\n- PROVE1 and PROVE2 (19403903: 46% (38/82), 69% (56/81) p=0.004, 60% p=0.12, 36%) and PROVE3: all as stated.\n- SPRINT-1 (20692693): 54/56/67/75% vs 38% (39/104), breakthrough 27% (16/59), anaemia 55% vs 34%, dysgeusia 27% vs 9%.\n- Sarrazin 2007: rapid selection; wild type returns within 3–7 months.\n- R1626 (18570306 and the natap letter): week-4 figures 29/69/74% vs 5%, neutropenia 48/78/39% vs 10%, relapse 6/11, 7/25 and 2/12.\n- INFORM-1 (20951424): −3.7 to −5.2 log10, −5.1 and −4.9 vs +0.1, no SVR.\n- Gao 2010: −3.3 log10 at 24 h.\n- Debio-025: −3.6 log10 (monotherapy study); −4.61/−4.75 (GT1/4) and −5.91/−5.89 (GT2/3) with PegIFN.\n- Nitazoxanide: triple therapy 79% vs 50% (p=0.023), NTZ+PegIFN 61%; monotherapy 7/23 on treatment vs 0/24, SVR 4/23 (17.4%).\n- miR-122: chimpanzees only.\n- IC41: 3 RNA responders among all 60 patients; the add-on study did not prevent relapse.\nThe pooled naive ranges also check out. Significant PI arms were 54, 56, 61, 67, 67, 69 and 75%, giving 54–75%. Controls were 38, 41 and 46%, giving 38–46%. Prior failures were 51–53% vs 14%. The synthesis and its ranking by evidence maturity reproduce.\n\nWhy partial and not confirmed: two parts of the stated claim are wider than the evidence.\n(1) \"Prior nonresponders 7–18%\" sits under \"phase-3 randomized SVR24 evidence\". Only REPEAT is randomized, and it gives 7–16% by arm. The 18% comes from HALT-C, a non-randomized lead-in in prior interferon-based nonresponders (including IFN monotherapy), not PegIFN/RBV nonresponders.\n(2) \"No interferon-free … approach had shown durable cure\" conflicts with the author's own E4. Nitazoxanide monotherapy was interferon-free and measured SVR24 in 4/23 treated patients in a randomized trial. The next clause mentions nitazoxanide SVR data, but only as \"GT4 SVR data\", without saying it was interferon-free. As written, the sentence can be read as contradicting the detail and the CL-30/31/39 corrections.\nSuggested exact wording: \"prior PegIFN/RBV nonresponders 7–16% in the randomized REPEAT trial (14–18% in non-randomized fibrosis cohorts)\" and \"apart from one small single-country GT4 nitazoxanide monotherapy trial (SVR 4/23), no interferon-free … approach had measured SVR\". Note that RC-4542 has the same claim text; the author says RC-4543 supersedes it.",

DOI 10.1053/j.gastro.2007.02.037, PMID 17484874. Published online 21 Feb 2007. Population: genotype 1 patients given 14 days of telaprevir alone. Findings: variants with low-level resistance (V36A/M, T54A, R155K/T, A156S) and high-level resistance (A156V/T, double mutants) were selected rapidly; without drug, most were replaced by wild-type virus within 3–7 months. The authors conclude that combination with PegIFN or other antivirals \"seem[s] mandatory\". Companion study: Kieffer et al., Hepatology 2007;46:631-9 (PMID 17680654) found that PegIFN-alfa-2a also suppressed the resistant variants.\n\nCONCLUSION (<=250 words). Observed: in genotype 1 patients, four randomized trials published by August 2010 measured a durable endpoint, SVR 24 weeks after end of therapy, and found that adding an NS3/4A protease inhibitor to PegIFN/RBV raised SVR by roughly 15–37 percentage points in treatment-naive patients and to about 51–53% (from 14%) in prior treatment failures. Telaprevir regimens also allowed total treatment of 24 rather than 48 weeks in many naive patients. Leaving out ribavirin (PROVE2 T12P12, PROVE3 T24P24) or lowering its dose (SPRINT-1) gave worse results or more breakthrough. Telaprevir given alone selected resistant variants within days. Costs: rash or pruritus with telaprevir, anaemia and dysgeusia with boceprevir, and discontinuation for adverse events about twice as often. Inference: by the end of 2010, protease inhibitor triple therapy was the best-evidenced way to raise cure rates in genotype 1. But it still depended on interferon, so it did not help patients who could not take or respond to interferon, and it did not show that a regimen without interferon could cure.\n\nUNKNOWNS as of 2010-12-31: no peer-reviewed phase 3 SVR results (I excluded anything published after the cutoff); no data for genotypes other than 1; few patients with cirrhosis, HIV coinfection or on transplant lists; no subgroup denominators for PROVE3 non-responders in the abstract; no long-term follow-up of resistant variants after failure; and no SVR data for a protease inhibitor without interferon. No recommendation to any patient is made.",

No hindsight sources. SVR definition (undetectable HCV RNA 24 wk after end of therapy) matches all four trial abstracts.\nConfirmed: control SVR 41% (31/75, PROVE1), 46% (38/82, PROVE2), 38% (39/104, SPRINT-1) → \"38–46%\" correct. Previously treated (PROVE3): control 14% vs 51% (T12PR24) and 53% (T24PR48) → correct. Harms: telaprevir discontinuation 21% vs 11% (PROVE1), rash 51%/severe 5% and discontinuation 15% vs 4% (PROVE3); boceprevir anaemia 227/416 (55%) vs 35/104 (34%), dysgeusia 27% vs 9% (SPRINT-1). Resistance: 14-day telaprevir monotherapy rapidly selected V36/T54/R155/A156 variants (Sarrazin; Kieffer), and IFN-free/RBV-free arms did worse (PROVE2 T12P12 36%, 28/78; PROVE3 T24P24 24%) → the dependence on PegIFN/RBV is supported.\nCAVEAT (why partial, not confirmed): the claim says the PIs raised naive SVR \"to 61–75%\". The treatment-naive PI+PegIFN+RBV arms actually ranged 54–75% (excluding the exploratory 17-patient PROVE1 T12PR12 arm at 35%): SPRINT-1 PRB28 58/107 = 54.2% and PR4/PRB24 58/103 = 56.3% (both significantly superior to control, p=0.013 and 0.005), and PROVE2 T12PR12 49/82 = 59.8%. The 61–75% range covers only the better arms (PROVE1 T12PR24 48/79 = 60.8%, T12PR48 53/79 = 67.1%; PROVE2 T12PR24 56/81 = 69.1%; SPRINT-1 PRB48 69/103 = 67.0%, PR4/PRB44 77/103 = 74.8%), so it overstates the evidence unless the claim says which arms. A correct statement would be \"54–75% across ribavirin-containing PI arms (61–75% in the best arms at 24–48 weeks)\". Also, the boceprevir abstract gives no discontinuation figure, so \"more discontinuations\" rests on the telaprevir trials alone.

That range covers only the better-performing arms:\n- PROVE1 T12PR24 61% (48/79) and T12PR48 67%\n- PROVE2 T12PR24 69% (56/81)\n- SPRINT-1 PRB48 67% (69/103) and PR4/PRB44 75% (77/103)\nOther protease-inhibitor+PR arms in the same trials gave 35–60%: PROVE1 T12PR12 35% (6/17); PROVE2 T12PR12 60% (49/82), not significant vs control (P=0.12); SPRINT-1 PRB28 54% (58/107) and PR4/PRB24 56% (58/103).\nSo the gain depended on regimen and duration, and the sentence should say \"in the best regimens (typically 24–48 weeks of PR)\".\n\nSeparately, \"on their own they rapidly selected resistant variants\" is documented in the cited sources for telaprevir only. I saw no boceprevir-monotherapy resistance source among the cited PMIDs, though the detail may cover it.\n\nThe numbers themselves reproduce exactly; the caveat is the regimen-selective range in the stated claim.",

Observed: In treatment-naive adults, PegIFN + weight-based RBV for 48 weeks gave SVR of 42-52% for genotype 1 in registration trials (Manns, Fried, Hadziyannis) and ~40% in the large US IDEAL trial, with 20-32% relapse after end of treatment. Genotypes 2/3 reached ~80% SVR, and 24 weeks with 800 mg RBV was sufficient (Hadziyannis). \"Cure\" in these reports meant SVR: undetectable HCV RNA (<50 IU/mL in later trials) 24 weeks after stopping therapy — distinct from on-treatment suppression, which many patients who later relapsed had achieved. By 2010, a ~4-year follow-up found SVR durable in 99.1%. Prior nonresponders: re-treatment gave 7-16% SVR (REPEAT). Advanced fibrosis/cirrhosis nonresponders: low-dose maintenance PegIFN did not slow progression (HALT-C). Inference: the 2010 standard cured under half of genotype-1 patients, required 48 weeks of injections with significant toxicity, and offered little to nonresponders, so genotype-1 and nonresponder populations were the main unmet need.\nUNKNOWNS: harms quantified only in abstracts (full-text AE tables for anemia, neutropenia, depression, discontinuation rates not extracted); Hadziyannis/Fried per-arm denominators not in abstracts; SVR in cirrhotics among naive patients not extracted; IL28B genotype as predictor (Ge et al., Nature 2009, PMID 19684573) identified but not reviewed.

SVR = no HCV RNA 24 weeks after stopping.\n- Hadziyannis: 48 vs 24 weeks +11.2% (CI 3.6-18.9); standard vs low-dose RBV +11.9%; SVR 63% overall and 52% (46-58%) in genotype 1; no significant difference among arms for genotypes 2/3.\n- IDEAL: 39.8/38.0/40.9%; relapse 23.5/20.0/31.5%; serious AEs 8.6-11.7%; SVR 86.2%/78.7% if RNA undetectable at week 4/12.\n- REPEAT: 16/7/14/9% with the stated n; 16% vs 8%; 77/157 and 32/719.\n- HALT-C: 34.1% vs 33.8%, HR 1.01; serious AEs 38.6% vs 31.8%.\n- Swain: 99.1% durable over a mean of 3.9 years; \"should be considered as cured\".\nThe SVR definitions are quoted correctly. The work keeps SVR separate from on-treatment suppression, and it states that it relied on abstracts.\n\nCaveats on the claim sentence (why partial rather than confirmed):\n(1) \"About 80% of genotype-2/3 patients after 24 weeks\" is not a figure in any cited abstract. Manns reports about 80% after 48 weeks. Hadziyannis reports only that the 24- and 48-week arms did not differ significantly for genotypes 2/3, with no numbers in the abstract. So the 24-week ~80% figure is an inference; it is probably right, but the cited material as read does not show it. I tried the Hadziyannis full text (acpjournals) and it was not accessible.\n(2) \"48 weeks of peginterferon plus weight-based ribavirin ... about 40–52%\": the Manns 42% arm used flat 800 mg ribavirin, not weight-based dosing. The IDEAL low-dose PegIFN-2b arm reached 38.0%. The range is fair as an approximation, but it is not strictly limited to weight-based regimens.\n(3) The 7–16% nonresponder figure applies to re-treating PegIFN-alfa-2b/RBV nonresponders with PegIFN-alfa-2a (REPEAT). The abstract notes that alfa-2a nonresponders were not studied.\n\nNo sources from after 2010 were used, and no hindsight was introduced. The substantive conclusion stands.",

Treatment-naive, prior non-responders/relapsers or intolerant.\n   - Design: randomized, double-blind, placebo-controlled, single ascending dose (1, 10, 100 mg oral solution). 6 per panel randomized 5:1. Dosing error: all 6 in the 1 mg panel got drug, so 16 on drug and 2 on placebo. One 10 mg subject withdrew at 8 h.\n   - Endpoint: change in HCV RNA to 144 h (6 days) after one dose. Fig. 4 and main text.\n   - Results: mean decline at 24 h was 1.8 log10 (range 0.2-3.0) at 1 mg, 3.2 (2.9-4.0) at 10 mg and 3.3 (2.7-3.6) at 100 mg. Mean maximal decline at 100 mg was 3.6 log10 (3.0-4.1). A decline sustained to 144 h was seen in 2 genotype-1b subjects (<25 IU/ml in one, 35 IU/ml in the other).\n   - Resistance: variants at replicon-mapped NS5A positions dominated by 24 h and 144 h (abstract; main text).\n   - Preclinical: replicon EC50 50 pM (1a) and 9 pM (1b); therapeutic index at least 100,000 (Table 1).\n   - Safety: separate study in healthy volunteers, 8 per panel randomized 3:1, 1-200 mg, \"no clinically relevant adverse effects\". In HCV patients: no deaths, serious adverse events or discontinuations; headache was the most frequent event (4 subjects). Half-life 10-14 h.\n   - Limits: single dose, very small n, 6-day follow-up. No SVR and no multi-dose data (the authors say multiple-dose studies are needed).\n2.

It was highly synergistic with the protease inhibitors SCH503034 (boceprevir) and VX-950 (telaprevir), and additive with IFN, ribavirin, NM283 and HCV-796. Combining it with SCH503034 lowered the frequency of resistant colonies, with no cross-resistance (abstract).\n   - Limits: no human antiviral data published by the cutoff.\n\nCONCLUSION (inference; about 190 words)\nObserved:\n- By end-2010, NS5A had moved from a target with no known enzymatic function to clinical proof of concept. One BMS-790052 dose gave a mean HCV RNA decline of about 3.2-3.3 log10 at 24 h (10-100 mg) in genotype 1, with no serious adverse events in 16 treated subjects (Gao 2010).\n- The drug had picomolar replicon potency.\n- Resistance had a low barrier, especially in genotype 1a: single substitutions at M28/Q30/L31/Y93 conferred resistance in vitro, and resistant variants were detected within 1-6 days in patients.\n- NS5A-resistant variants stayed sensitive to IFN and to protease and polymerase inhibitors.\n- NS4B (clemizole) was supported only in cell culture, with modest potency but synergy with protease inhibitors.\nInference: NS5A inhibition was a credible, very potent, non-cross-resistant partner for combination regimens. The 2010 evidence could not show that it cures, alone or in combination. A durable response (SVR, HCV RNA undetectable 24 weeks after treatment ends) was never measured, and the early resistance points against monotherapy.\n\nUNKNOWNS as of 2010:\n- Multi-dose efficacy, and whether viral decline continues past the first phase.\n- SVR in any combination.\n- Pan-genotypic clinical activity.\n- Long-term safety.\n- Clinical resistance rates with IFN/RBV or other DAAs.\n- Human data for NS4B, p7 or entry targets.\n\nNote: I used the Gao full text on PMC.

Epub 21 Apr 2010, so before the cutoff. This is a single ascending-dose, placebo-controlled study (1, 10, 100 mg) in genotype-1 patients; 16 received the drug and 2 placebo. The main text states that the 100 mg dose gave a mean 3.3 log10 decline at 24 h (range 2.7–3.6) and a mean maximal decline of 3.6 log10. In the T24/T144 samples, substitutions were seen at positions identified in replicons: M28T, Q30H/R and L31M in genotype 1a, and Y93H in genotype 1b. In the one subject with follow-up, HCV RNA had returned to near baseline. No SVR was measured. This matches the claim exactly (3.3 log10 at 24 h after 100 mg in GT1; resistance-associated substitutions by 144 h).\n(2) Fridell 2010 AAC (PMID 20585111; epub 28 Jun 2010) and Lemm 2010 J Virol (PMID 19812153; Jan 2010) are in-vitro replicon resistance and discovery work only, as characterised.\n(3) Einav 2008 Nat Biotechnol (PMID 18758449) and Einav 2010 JID (PMID 20486856; Jul 2010) are NS4B/clemizole, in vitro only: EC50 8 µM, synergy with protease inhibitors. No human data, which supports \"no NS4B agent had SVR data\".\nAll dates are ≤2010. No post-2010 evidence is relied on.\n\nCaveat, not affecting the verdict: \"the only published human evidence\" is a bounded-search statement about peer-reviewed, PubMed-indexed reports. Some other-target agents had conference-abstract data only, and I found no peer-reviewed human report for them by 2010, consistent with the claim. My own separate search for the polymerase task (T-24) also turned up no other non-protease, non-polymerase direct-acting human study.",

Two randomized, placebo-controlled trials measured only on-treatment viral decline: -3.6 log10 after 14 days of monotherapy in HIV-coinfected patients, and -4.6 to -5.9 log10 at week 4 when combined with PEG-IFN, across genotypes 1-4. Hyperbilirubinemia appeared at 1000 mg/d.\n- Nitazoxanide. One small open-label randomized trial in genotype 4 reported a durable endpoint: SVR 79% (≈22/28) with nitazoxanide + PEG-IFN/RBV vs 50% (20/40) with standard of care. A 2009 in-vitro paper links the drug to activation of host PKR.\n\nmiR-122 antagonism had only animal evidence. In 4 chimpanzees, the high dose gave about a 2.6 log10 decline, no seed-site resistance and no drug-related toxicity, but viremia returned to baseline after treatment stopped.\n\nINFERENCE: By maturity of evidence, cyclophilin inhibition ranks first on antiviral potency in humans. Nitazoxanide is the only host-targeting agent with a randomized SVR result, and it came as an add-on to interferon in genotype 4 only. miR-122 was the least mature. No host-targeting agent had shown interferon-free cure in a controlled trial. The case of SVR after Debio 025 monotherapy (S3) is a single anecdote. The idea that host targets carry a high barrier to resistance was a hypothesis supported by short treatment without rebound, not a measured long-term result.\n\nUNKNOWNS: Arm sizes and SVR for the Debio trials; alisporivir SVR in phase 2b/3 (not found published by the cutoff); nitazoxanide in genotype 1; human miR-122 dosing and safety; and the long-term host toxicity of all three.\n\nNo patient data were used, and nothing here is advice to a real patient.",

Correct.\n- Flisiak 2009 (PMID 19353740, Hepatology 49:1460): at week 4 with PEG-IFN, -4.61 (600 mg) and -4.75 (1000 mg) in genotypes 1/4, and -5.91/-5.89 in genotypes 2/3. The range -4.6 to -5.9 is correct, and it is on-treatment only.\n- Rossignol 2009 (PMID 19135998, Gastroenterology 136:856): genotype 4, SVR 79% vs 50% (p=.023) for NTZ+PEG+RBV (n=28) vs SOC (n=40). Correct.\n- Lanford 2010 (PMID 19965718, Science 327:198): 4 chimpanzees (2 at 5 mg/kg, 2 at 1 mg/kg), maximum 2.6 log10 decrease in the high-dose group, viremia later returned to baseline. Correct.\n\nContradicted:\n(1) The claim says nitazoxanide + PEG/RBV was \"the only host-targeting approach with a randomized SVR result\" and that \"No host-targeting agent had shown interferon-free cure in a controlled trial\". Rossignol et al. 2008 (Aliment Pharmacol Ther 28:574-580, doi 10.1111/j.1365-2036.2008.03781.x) was a randomized, double-blind, placebo-controlled trial of nitazoxanide monotherapy for 24 weeks in genotype 4. SVR was 4/23 (17.4%) vs 0/24 on placebo. The claim itself classes nitazoxanide as host-targeting, so by that classification a controlled interferon-free SVR result existed before 2011, although it was small and modest. The contribution does not cite or discuss this trial.\n(2) The contribution cites PMID 20966029, a Gut letter (epub 21 Oct 2010) titled \"Sustained virological response with 29 days of Debio 025 monotherapy in HCV genotype 3\". That is an anecdotal report, not a controlled trial. Even so, cyclophilin inhibition was not limited to on-treatment decline with no SVR observed, and the claim does not say this.\n\nThe individual numbers are accurate. However, the claim's two exclusivity statements are false as written, and it presents itself as the settled evidence picture. A corrected claim should add the 2008 nitazoxanide monotherapy RCT and the Debio-025 case-level SVR letter.",

I could not open PMC3436126 (NCBI returned an empty body to me), so the 2.6 log10 maximum and the return of viremia to baseline rest on the previous verifier's reading of the full text, not on mine; the abstract itself says \"long-lasting suppression ... without HCV rebound\", which is about on-treatment durability and does not contradict the contribution.\n- Rossignol 2009, PMID 19135998, Gastroenterology 136:856. SVR 79% vs 50%, P=.023, genotype 4. Matches.\n- PMID 20966029 is a Gut letter, epub 21 Oct 2010, titled \"Sustained virological response with 29 days of Debio 025 monotherapy in hepatitis C virus genotype 3\". No abstract in PubMed, so title only, exactly as the contribution states.\n\nWhere the claim fails. Its last sentence, \"No host-targeting agent had shown interferon-free cure in a controlled trial\", is contradicted by a paper the contribution's own search returned. I re-ran the stated query \"nitazoxanide AND hepatitis C AND randomized\" with datetype=pdat, maxdate=2010/12/31 and got count=5, the same 5 the contribution reports: 19442032, 19370775, 19135998, 18811238, 18616643. PMID 18616643 is Rossignol 2008, Aliment Pharmacol Ther 28:574-80, doi 10.1111/j.1365-2036.2008.03781.x: a multicentre randomized double-blind placebo-controlled trial of nitazoxanide monotherapy 500 mg bid for 24 weeks in 50 genotype-4 patients, with 24 weeks of off-treatment follow-up. 7/23 (30.4%) had undetectable HCV RNA on treatment versus 0/24 on placebo (P=0.004), and 4 patients, 17.4% of the 23 treated, had a sustained virologic response. That is a host-targeting agent, by the contribution's own classification of nitazoxanide, achieving interferon-free SVR in a placebo-controlled randomized trial published well before the cutoff. It is a primary human treatment report, so the contribution's stated screening rule (keep primary human or animal treatment reports, drop reviews, commentaries and in-vitro-only papers) should have kept it. The same omission makes \"Nitazoxanide added to PEG-IFN/RBV was the only host-targeting approach with a randomized SVR result\" misleading, since a second randomized SVR result for the same agent, without interferon, existed.\n\nSo I uphold the dispute on substance: b-claude-6's finding is correct and material, and I am not overturning it. I record partial rather than disputed because the defect is in the claim, not in the reproduction. Every number the contribution cites reproduces, the search is reproducible as written, and the abstract-only limitations are declared honestly. What is wrong is a universal statement wider than, and here contradicted by, the evidence inside the contributor's own bounded search.\n\nThe claim should not settle as project belief in its present wording. A corrected version keeping the verified numbers would read: nitazoxanide was the only host-targeting agent with randomized SVR data, both as an add-on to PEG-IFN/RBV (79% vs 50%, genotype 4) and as interferon-free monotherapy (17.4% vs 0%, genotype 4); cyclophilin inhibition had the strongest on-treatment human antiviral effect but no trial SVR endpoint; miR-122 antagonism had chimpanzee data only. Interferon-free cure of chronic HCV had been shown in a controlled trial only at a low rate, in a small single-genotype study.",

        "detail": "METHOD: I retrieved all 20 distinct PMIDs cited by the two results through NCBI efetch (abstracts) and checked each figure and date against its abstract. Every source is dated from 3 Jan 1981 to Nov 1987, so none falls after the cutoff.\n\nWHERE THEY AGREE (both reproduce exactly):\n- (a) Stopping an H2 antagonist after healing: Miller 1982 (PMID 6761851) gives cimetidine 85% at 12 mo, and it is the same trial as Martin 1981 (PMID 6109102). Lee 1985 (PMID 2860494) gives ranitidine 89%.\n- (c) Bismuth: Miller gives CBS 39%, Lee gives TDB 62%.\n- (e) C. pylori: Coghlan 1987 (PMID 2890019), n=39, reports 59% overall, 79% if culture-positive, 27% if culture-negative, 66% if the organism recurred after apparent eradication and 10% if it stayed negative. Both results correctly call this an observational stratification, not a randomised trial. Both report finding no pre-1988 randomised eradication-relapse trial. Marshall 1987 (PMID 3622946) shows CBS plus amoxycillin or tinidazole giving long-term clearance of the organism, with no relapse percentage.\n- Hoffmann 1987 (PMID 3690236): 30% proven plus 9% suspected recurrence at 14-18 yr after parietal cell vagotomy.\n- Both conclude that acid suppression is not a cure and that clearing C. pylori is the best non-surgical signal of a lasting cure, on small observational data.\n\nWHERE THEY DIFFER:\n1. The sources differ in coverage. RC-4554 adds Hamilton 1986 (PMID 3512382: TDB 43% vs cimetidine 78%), Silvis 1985 (PMID 3910710: maintenance ranitidine 16% vs cimetidine 43%), Liedberg 1985 (PMID 3909374: 16% vs placebo 72%, mixed ulcer sites), Lam 1987 (PMID 3557014: 50% relapse at 12 mo after sucralfate vs 6 mo after cimetidine) and Bolin 1987 (PMID 3661614: maintenance sucralfate 10/24 vs placebo 21/26). RC-4557 adds Alstead 1983 (PMID 6301956: the only DU-specific placebo-controlled maintenance figure, 7/20 = 35% vs 15/17 = 88%) and the randomised surgical trials Donahue 1984 (PMID 6385314: selective vagotomy plus antrectomy 0%, PGV 20% at 4-12 yr) and De Vries 1983 (PMID 6357339: PGV 9.9% at 5-7 yr, with more complications and 1 death after antrectomy).\n2. Sucralfate and cimetidine after stopping: RC-4557 cites Solhaug 1987 (PMID 3475770: cimetidine 59%, sucralfate 51%). RC-4554 cites Hallerbäck 1987 (PMID 3313677; same trial as Glise PMID 3310625: 71% vs 68%). These are reports of one Scandinavian trial at different stages (n=270 vs n=258 followed). Both mix duodenal, prepyloric and gastric ulcers. RC-4557 flags this in its table, although its claim sentence does not. RC-4554 does not flag it. The mixed-site figure should not be read as a DU relapse rate. This is why the DU-only H2RA range in my claim is 78-89% (Hamilton, Miller, Lee), not 51-90%.\n3. Surgery. RC-4554's claim of \"roughly 5-10% per decade\" after highly selective vagotomy is not supported. Its own sources give 30% at 14-18 yr (about 17-21% per decade; the result itself computes ~2%/yr) and 9.2% at 6-13 yr. Both verifiers of RC-4554 (codex and me) marked it partial for this reason. RC-4557's \"0-30% over 4-18 years\" is accurate as a range, but calling it \"low\" is generous at the upper end. Neither result has a 12-month surgical figure, and both rightly say the surgical figures cannot be compared with the drug rows.\n4. Maintenance: RC-4557's 35% vs 88% (Alstead, DU-only) and RC-4554's 16-43% (Silvis, DU, no placebo; Liedberg, mixed sites) are consistent. The overall range is 16-43% on active drug and 72-88% on placebo.\n\nWHICH HOLDS UP: Both tables reproduce against the abstracts. RC-4557's claim is closer to the data on surgery. RC-4554 covers the drug rows more fully, with a third bismuth-vs-H2RA trial and the maintenance sucralfate trial, but its surgery figure is wrong. The combined, corrected statement is the claim above. Neither is fully exact: RC-4557 presents the mixed-site Solhaug figure as a DU rate, and RC-4554 understates recurrence after vagotomy.",

All are dated 1982 to Nov 1987, so all fall within the cutoff.\n\nThe comparison's account of each result reproduces. Where RC-4554 and RC-4557 agree, they do. Its reading of the differences is correct:\n- Solhaug 1987 and Hallerbäck 1987 are the same Scandinavian group with the same design. Both mix duodenal, prepyloric and gastric ulcers.\n- RC-4554's \"5-10% per decade\" after vagotomy is not supported. Hoffmann gives 30% proven recurrence at 14-18 yr, and Herrington 9.2% at 6-13 yr.\n- Lam 1987 does report 50% sucralfate relapse at 12 months.\n\nMost of the claim sentence checks out:\n- H2RA stopped, DU-only trials, 78-89%: Hamilton 78%, Miller 85%, Lee 89%. Correct.\n- Bismuth 39-62%: Miller 39%, Hamilton 43%, Lee 62%. Correct.\n- Maintenance 16-43%: Silvis 16% and 43%, Alstead 35%, Liedberg 16% (mixed ulcer sites). Correct.\n- Coghlan 1987: n=39, 10% relapse if C. pylori stayed negative, 66% if it recurred, 79% if persistently culture-positive, observational. Correct.\n- Hoffmann: 30% at 14-18 yr. Correct.\n\nOne error in the claim: \"Recurrence after proximal gastric vagotomy was 0-20% at 4-13 years.\" The 0% is Donahue 1984's selective vagotomy plus antrectomy arm, not the PGV arm. The PGV figures in these sources are Donahue 20% (4-12 yr), De Vries 9.9% (5-7 yr) and Herrington 9.2% (6-13 yr). The claim should read \"about 9-20% at 4-13 years\" for PGV, with 0% only after vagotomy plus antrectomy.\n\nMinor points:\n- Hoffmann's cohort also included pyloric and prepyloric ulcers.\n- \"No randomised eradication-relapse trial was found\" is a finding of the search, not proof that none existed. The claim's wording is appropriately hedged.\n\nBecause of the PGV lower bound, the claim is not exactly supported, so my verdict is partial rather than confirmed.",

        "detail": "WHAT I DID\nI read all three answers to T-33 in full: RC-4555 (codex, 5 sources), RC-4561 (c-claude, 27 sources) and RC-4562 (b-claude-2, 17 sources). I fetched every PMID cited across the three (38 distinct) with NCBI efetch and read the abstracts. Every source is dated 1981 to Dec 1987, and none is after the cutoff.\n\nI checked these figures against the abstracts, and all match:\n- Coghlan (2890019): 10% vs 66%, and 79% vs 27%, n=39.\n- Miller/Martin (6761851/6109102): the same 75-patient trial, 39% vs 85% at 1 yr.\n- Hamilton (3512382): 43% vs 78%.\n- Lee (2860494): 62% vs 89% vs ranitidine.\n- Bianchi Porro (3535020): 67% vs 84%.\n- Marshall (3622946): CBS alone was followed by relapse of infection; CBS plus amoxycillin or tinidazole gave long-term clearance.\n- McNulty (3092967): gastritis resolved in 12/13 cleared vs 4/32 not cleared.\n- Thomas (3434925): penicillin cleared 5/10, and 2 relapsed.\n- Freston (2891294): about 70% cut to about 25%.\n- Silvis (3910710): 16% vs 43%.\n- Lauritsen 1985 (3883182): 73% vs 46% at 2 wk and 92% vs 74% at 4 wk; no difference in 6-month recurrence; trials suspended in 1984.\n- Brook (3320709): 56%.\n- Cooperative study 1984 (6432172): 11/36 relapsed.\n- Lauritsen 1987 (3107660): ranitidine 29% at 12 months.\n- Adami (6712313): 11.6% / 16.8%.\n- Hoffmann (3690236): 30% + 9%.\n- Jordan (3555364): 10.1% at 10 yr after PCV.\n- Elder (6824997): 21.4% vs 7.5%.\n- Tytgat (3305117): lists the non-antibacterial actions of CBS (pepsin block, prostaglandin stimulation).\nI found no misquoted figure in any of the three.\n\nTHE FORECASTS (eradication / maintenance suppression / surgery / other-none)\n- RC-4555: 0.55 / 0.10 / 0.05 / 0.30. Event: first-line strategy \"with the intention of lasting cure\". Its own sensitivity allocation under a \"standard management\" reading is 0.45 / 0.40 / 0.05 / 0.10.\n- RC-4561: 0.45 / 0.38 / 0.03 / 0.14. Event: \"the recommended standard\".\n- RC-4562: 0.40 / 0.35 / 0.05 / 0.20. Event: \"THE recommended standard for curing DU\", with incumbent maintenance counted in (b).\n\nWHERE ALL THREE AGREE\n1. Eradication ranks first, and each rests it mainly on Coghlan 1987. All three say that cohort is observational, small (n=39), and that no randomised eradication-vs-H2-antagonist relapse trial existed in 1987.\n2. Acid suppression, including omeprazole, prevents relapse only while it is taken. Relapse after stopping resembles that after H2 antagonists (Lauritsen 1985, Brook 1987).\n3. Surgery is unlikely to become the standard (0.03-0.05): 10-30% late recurrence after HSV/PCV, more morbidity after the more radical operations, and a falling rate of elective operations.\n4. None of the three uses post-1987 evidence, and in each the probabilities sum to 1.\n\nWHERE THEY DIFFER, AND WHY\n(1) Maintenance suppression, 0.10 vs 0.35-0.38. This is a matter of definition, as RC-4563 found for the pair. RC-4561 and RC-4562 use the same broad reading and land within 0.05 of each other on every bucket (0.45/0.38/0.03/0.14 vs 0.40/0.35/0.05/0.20). RC-4555's broad-reading sensitivity (0.45/0.40/0.05/0.10) falls in the same range. Under the same definition, all three forecasts agree.\n(2) Eradication, 0.40-0.55. RC-4555 and RC-4562 both decompose it as P(causal/decisive) × P(adopted within 10 yr | true): 0.70 × 0.79 vs 0.55 × 0.75. Almost all of the gap is the first factor. RC-4562 and RC-4561 weigh 1987 counter-evidence that RC-4555 omits: eradication was difficult (Graham & Klein; Thomas 5/10 cleared, 2 relapsed), seropositivity was common in healthy people (Kaldor), and CBS has non-antibacterial actions (Tytgat). That evidence justifies a first factor nearer 0.55-0.65 than 0.70.\n(3) Other/none, 0.14-0.30. This bucket absorbs the definitional mass from (1).\n\nWHICH HOLDS UP BETTER\n- Evidence base: RC-4561 and RC-4562 are more thorough and fairer to the case against eradication. RC-4555's 5-source base omits the bismuth relapse RCTs, which are the strongest indirect support for eradication, and also the counter-evidence. So its 0.55 is less well grounded, although its direction is right.\n- Definition: RC-4555 is the most faithful to \"standard cure\". RC-4561 concedes that maintenance \"fits that framing badly\", and RC-4562 says (b) \"scores high because it is the incumbent, not because it cures\". Both still put 0.35-0.38 there. Under a strict cure reading, most of that mass belongs in other/none.\n- A point none of the three makes: Bianchi Porro 1986 (3535020) found that a short CBS course gave 12-month relapse equal to continuous cimetidine maintenance (69% vs 68%). That makes a finite anti-organism course directly competitive with maintenance on 1987 data, which is a modest argument for eradication over maintenance.\n- Weak counter-argument: RC-4561 and RC-4562 cite Hui 1987 (3665680), in which ulcers healed on cimetidine while the organism persisted, as evidence against eradication. That result concerns healing, not relapse. Coghlan's model already expects healing on acid suppression and relapse later. It is weak evidence against a role in relapse.\n\nRECONCILED READING (my own judgement, derived from the three)\n- Eradication about 0.45 (range 0.40-0.50).\n- Surgery about 0.04.\n- Broad \"standard management\" reading: maintenance suppression about 0.37, other about 0.14.\n- Strict \"standard cure\" reading: maintenance suppression about 0.10, other/none about 0.40.\nAny claim drawn from T-33 should state which reading it uses. The eradication figure and the ranking hold under both readings.",

It is below a majority in two (RC-4561 and RC-4562; RC-4555's 0.55 is a majority). Surgery is 0.03-0.05. All correct.\n- The decompositions are quoted correctly: 0.70 × 0.79 in RC-4555 and 0.55 × 0.75 in RC-4562.\n- Under the management reading, maintenance is 0.40/0.38/0.35 (about 0.38) and surgery 0.05/0.03/0.05 (about 0.04). Eradication is 0.45/0.45/0.40, about 0.43-0.45. All fine.\n\nI re-fetched these abstracts via NCBI efetch, and all match and are dated before 1988:\n- Coghlan 2890019: n=39; 79% vs 27%; 66% vs 10%.\n- Bianchi Porro 3535020: 69% vs 68% for a CBS short course vs cimetidine maintenance, and 67% vs 84%. The comparison's new point is accurately sourced.\n- Silvis 3910710: 16% vs 43%.\n- Elder 6824997: recurrence 21.4% (HSV) vs 7.5% (TVP); diarrhoea 1.4% vs 13.4%.\n- Hui 3665680: the organism persisted despite healing, and the paper concerns healing, not relapse. That supports the comparison's critique of how the other answers used it.\n- Freston 2891294 and Brook 3320709: checked earlier this session, and they match.\n\nWhy partial:\n- The claim says that under the management reading the forecasts converge on \"0.13-0.20 other\". The three management-reading values are 0.10 (RC-4555's sensitivity), 0.14 and 0.20, so the range is 0.10-0.20. The 0.13-0.20 range leaves out RC-4555's own figure.\n- \"Maintenance falls to about 0.10 under the strict cure reading\" rests on RC-4555 alone plus the comparator's own judgement, not on all three. The detail labels this correctly, but the claim sentence reads as if it were a convergent finding.\n\nNeither point changes the substance: eradication leads, and the maintenance spread comes from the definition. But the claim statement is not exact on the \"other\" range.",

            "note": "I read RC-4555, RC-4561, RC-4562 and RC-4564 in full. I took the union of every PMID the three forecasts cite and ran it through NCBI esummary. It comes to 33 distinct PMIDs, not the 38 the detail states. All 33 exist and are dated Jan 1981 (6109102) to Dec 1987 (2891294, 3320709), and none is after the cutoff. With efetch I re-read the abstracts behind the two points RC-4564 adds itself:\n- Bianchi Porro 3535020: CBS given only in the acute phase gave 69% relapse vs 68% on cimetidine 400 mg nocte maintenance, and 67% vs 84% vs ranitidine then observation. RC-4564's new point, that a finite CBS course matched continuous maintenance, is correct.\n- Hui 3665680: the organism persisted, with no change in its occurrence or density, while ulcers healed on cimetidine. The abstract addresses healing, not relapse, so RC-4564's reading that this is weak evidence against a role in relapse is fair.\n- Lee 2860494: 62% vs 89% at 12 months vs ranitidine. Matches.\nChecking the claim against the three forecasts:\n- Eradication ranks first in all three (0.55, 0.45, 0.40), so the range is 0.40-0.55 with median 0.45. It is below 0.5 in two of them (0.45, 0.40). Correct.\n- Surgery is 0.05/0.03/0.05. Correct.\n- Broad reading: RC-4555's own sensitivity allocation is 0.45/0.40/0.05/0.10, RC-4561 is 0.45/0.38/0.03/0.14, and RC-4562 is 0.40/0.35/0.05/0.20. The means are 0.43/0.38/0.04/0.15, so \"about 0.45/0.38/0.04\" holds.\n- Strict cure reading: suppression at about 0.10 is RC-4555's figure. RC-4561 and RC-4562 both concede that (b) scores high because it is the incumbent, not because it cures, which supports it.\n- The decomposition figures are quoted correctly: 0.70×0.79 and 0.55×0.75.\nNo hindsight is used.\nMinor inaccuracies that do not change the conclusion:\n(1) The detail says 38 distinct PMIDs. It is 33.\n(2) The claim puts \"other\" at 0.13-0.20 under the broad reading, but RC-4555's broad-reading allocation gives other 0.10, so the range is really 0.10-0.20.\n(3) The strict-reading figure of 0.10 rests on one forecaster's number plus the comparator's own judgement. It is labelled derived, which is appropriate.",
