Fit: sm.GLM(y/n, X, family=Binomial(), var_weights=n).fit(scale='X2', tol=1e-12, maxiter=200). Dispersion = Pearson X2/df_resid (df_resid 77 for 84 donors, 66 for 73). Wald p = two-sided normal on coef/SE (q uses this); I also give p_t (t on df_resid, as R summary.glm) and its BH q_t. BH (fdr_bh) over the 130 tested supertypes, separately per term and per run. Sensitivity 'excl severe' keeps the same 130 supertypes, 73 donors.\n\nIMPORTANT for checkers (and the task's how_to_check): in statsmodels 0.14.5, sm.GLM(np.column_stack([y, n-y]), X, Binomial()).fit(scale='X2') returns the SAME coefficients but a dispersion on the wrong scale (Sst_3: 0.00296 instead of 33.498) and SEs about 100x too small, which makes ~127/130 interactions 'significant' with p≈0. My first run did exactly this; I caught it and switched to proportion endog + var_weights=n. The code asserts that res.scale equals sum((y-n*mu)^2/(n*mu*(1-mu)))/df_resid to 1e-8. Independently, a plain-numpy IRLS refit (crosscheck_irls.py) of all 130 x 3 runs agrees: max |d coef| 5.2e-10, max |d SE| 5.1e-10, max relative d(dispersion) 4.6e-10. This var_weights form is what R glm(cbind(y, n-y) ~ ..., family=quasibinomial) computes.\n\nRESULTS\nMain (carrier, 84 donors): interaction q < 0.10: none.

Sst_* family: 15 of 16 interactions negative (only Sst_11 positive), 1 of 16 nominal p < 0.05 (Sst_9); none q < 0.10.

CPS_Local q < 0.10: 10; APOE4: 0.\nReading: the Sst_* interactions lean negative (steeper loss with local pathology in carriers) but, with 25 carriers and Pearson dispersions of 3 to 34 in that family, no single Sst supertype's interaction survives multiple testing; I do not test the sign pattern (supertype shares are compositional and correlated, so 15/16 is not an independent-sign test).

The authors conclude 'Partial or short-term amyloid removal did not show significant clinical effects. However, long-term full amyloid removal potentially delayed symptom onset' (external controls).\n\nREASONING [derived]\n1) What a win requires. S3 gives 434 events and S4 a Cox model. I assume 1:1 allocation (S2 says only 'assigned randomly to receive either donanemab or placebo'), two-sided alpha 0.05 and no large interim alpha spend. Then SE(log HR) ≈ 2/sqrt(434) = 0.096, and a significant result needs an observed HR ≤ exp(-1.96 × 0.096) ≈ 0.83. Power by true HR: 0.61 → 1.00; 0.70 → 0.96; 0.75 → 0.85; 0.80 → 0.64; 0.85 → 0.39; 0.90 → 0.19; 1.00 → 0.02. Because the design is event-driven, lower enrolment (S3) delays the readout rather than cutting power.\n2) Anchor. Donanemab's CDR-G HR in symptomatic AD is 0.61–0.63 (S5), and in the 3-year early- vs delayed-start comparison it is 0.73 (S6). Earlier disease responded better in TRAILBLAZER-ALZ 2 (S2, S5), and this cohort sits earlier still, with less tau and less amyloid (S2). That argues for a core HR near or below 0.65 for the part of progression that amyloid removal can modify.\n3) Discounts on that core effect.\n(a) Dose. There are only nine monthly infusions (S2). In TRAILBLAZER-ALZ 2 just 34% had cleared at 24 weeks (S5), so some treated participants will be only partly cleared at the end of dosing. Partial or short removal showed no clinical effect in DIAN-TU (S10), and benefit tracks how low amyloid gets (S7). Against this, baseline amyloid is lower (63 CL), finishing treatment by 52 weeks gave similar slowing (S6), and reaccumulation is slow (S6).\n(b) Endpoint dilution. In cognitively unimpaired people aged 65–80, some CDR 0 → >0 transitions come from things plaque removal cannot change: co-pathology, mood, intercurrent illness, and noise in remote ratings (S2, S4). The two-consecutive-assessment rule (S2) reduces the noise but does not remove it. If 20–40% of events cannot be modified, a core HR of 0.61–0.70 becomes an observed HR of roughly 0.69–0.82.\n(c) Timing. Hazards may not be proportional: after a short course, separation may come late, and the Cox HR averages over up to about 6 years.\nFrom (a)–(c) my central true HR is 0.77, with a log-scale SD of 0.14. Combining that with the sampling SE of 0.096 gives P(observed HR ≤ 0.83) = 0.67. Sensitivity: a central HR of 0.75 gives 0.72, and 0.80 gives 0.58; an SD of 0.10 gives 0.70, and 0.18 gives 0.64.\n4) Shading for what the model leaves out. No preclinical or prevention anti-amyloid trial has yet met its primary endpoint (S8 A4, S9 API ADAD, the S10 double-blind phase). Those drugs did not clear plaque, though, so this is a weak base rate for a drug that clears it (S9's own conclusion). This would be the first preclinical positive, and it is run largely remotely (S2, S4). I therefore take about 0.09 off the model's 0.67, giving 0.58.\n5) What would change this. A disclosed allocation ratio, the interim-analysis plan, or the power assumptions. Any AHEAD 3-45 readout. Evidence on how many participants had cleared amyloid by the end of dosing. Any Lilly statement on timing.\n\nPRIOR ART, re-run 2026-09-30: I found no open probability for this outcome and no reported result.

The stated 85 anti-amyloid-antibody denominator reproduces when ABBV-1758 (the registry name corresponding to the detail's ALIA-1758) is included, giving the claimed 4/85 versus 5/898 split. However, the required per-trial classification is slightly wrong for five regex-positive records: NCT02569398, NCT04032626, NCT04468659, and NCT04601038 use APOE4 as one of several alternative qualifying eligibility routes, and NCT01931566 excludes people when their TOMM40/APOE genotype is already known to preserve blinding.

They belong in the nonrestricting/genotyping bucket (with an ALT or blinding note), not 'mention not about eligibility'.

The q<0.10 sets are the same under both. BH is over all 130 tested supertypes, separately for the interaction, CPS_Local and APOE4 terms. Supertype set fixed from all-donor totals in every run. All fits converged. No randomness.\nWARNING FOR CHECKERS: in statsmodels 0.15.0, GLM with a two-column (successes, failures) endog and fit(scale='X2') returns a wrong scale (Sst_3: 0.00296 against Pearson X2/df = 33.50).

Age at death ranges 65–102.\n- All 84 MTG CPS donor IDs join.\n- Sex, age, APOE and severity are constant within each donor, and each supertype lies in one division (I asserted both).\n\nCOUNT TABLE: my donor × supertype table (groupby/unstack/sort, to_csv with '\\n') has SHA-256 69cdfe3f1dda26506fc3d5e9112a608a1ff9adebc8b5208b6223a2daf27382ba, identical to the submitted digest.\n\nMODEL: y/n ~ const + CPS_Local + E + CPS_Local·E + male + age + 10xMulti share in the division, where E is carrier status or dose. Binomial logit with Pearson X²/df dispersion. My IRLS and statsmodels GLM(y/n, var_weights=n).fit(scale='X2') agree to <4e-13 on coefficients and SEs in all three runs.\n\nAGREEMENT:\n- I parsed all 130 primary interaction coef/SE/p triples from the detail (including the 16 Sst), and every one matches mine at the reported precision (0 mismatches).\n- Primary: no interaction q<0.10. Min q is 0.13995 (Astro_4: 7.551851, SE 2.309636). 5 have p<0.05 and 67/130 are negative. Sst: 15/16 negative, and only Sst_9 has p<0.05 (−1.350251, SE 0.672869, p 0.0448), with min Sst q 0.723. CPS main q<0.10: the same 21 supertypes. APOE4 main: none.\n- Excluding severe donors (73): none at q<0.10, min q 0.102755 (Astro_4). 7 have p<0.05 and 70 are negative. Sst_9 and Sst_19 have p<0.05. CPS list: the same 7.\n- Dose: only Astro_4 at q<0.10 (4.753145, SE 1.322455, q 0.042304, positive). 10 have p<0.05 and 65 are negative. 13/16 Sst negative. CPS list: the same 10.\n- The q<0.10 sets do not change if p comes from t(df_resid) instead of the normal: primary and excl-severe are still empty, and dose is still Astro_4 only (q_t 0.074).\n\nCLAIM: every figure in the claim sentence reproduces. The sentence limits 'does not differ' to the BH q<0.10 threshold, so it says no more than the work shows.\n\nLIMIT: the author's analysis.py and results CSVs are declared by digest only (not hosted), so I could not diff those files.

Inputs: I downloaded all 17 MPD ITP1 workbooks on 2026-09-30 from the getcurationfile URLs in the task's sources_hint, and every SHA-256 matches the task's pins exactly. Pooled data: 36,975 mice, sites TJL/UM/UT, dead 0/1 (35,297 events, 1,678 censored 'removed'). Columns Rx(ppm)/age_initiation(mo)/age(days) in C2018-C2020 were renamed to dose/age_initiation/age.\n\nMethod: my own Weibull AFT maximum-likelihood code, not lifelines. It uses the survreg parametrisation (log T = Xb + sigma*W, W standard min-extreme-value; design = intercept + treated + site dummies), Newton-Raphson with an analytic gradient and Hessian in (b, log sigma), and Wald SE from the observed information. Max |gradient| at the MLE across the 182 fits was 1.7e-11. Controls are the same cohort's Control mice of the same sex, pooled over sites. Event = dead==1, everyone else censored at age.

These trials are 'genotyping required but no restriction' and carry a note.\n(2) A trial that states 'no ε4' both as inclusion and exclusion is 'requires no ε4'. No trial fell in 'excludes all ε4 carriers'.\n(3) NCT07794670 (SPINOZA, obicetrapib, start 2026-09) says only 'APOE genotype not meeting protocol-defined eligibility criteria'. The sponsor's release of 2026-09-29 (company statement, read 2026-09-30) says 'Enrollment is restricted to participants with ApoE4/E4, ApoE3/E4, or ApoE3/E3 genotypes'. That excludes ε2 carriers, which fits none of the task's categories, so it is reported as a 10th category, 'other genotype restriction'. It does not exclude ε4/ε4.\n(4) The regex hit in NCT06563895 is TTR homozygosity (not APOE); NCT05551741 says 'regardless of APOE gene status'; NCT01767311 lists APOE4-positive participants taken off 10 mg/kg as allowed into the extension. All three are 'mention not about eligibility'.\n(5) NCT03887455 (Clarity AD) excludes ε4/ε4 only from Extension Part B, and only in countries where the label excludes homozygotes. It is counted as 'excludes ε4/ε4 only' with a 'conditional' note.\n(6) NCT05965414 is a quota: ε4 is required for, on average, at least 4 subjects per MAD cohort.\nSupplementary check of all 913 regex-negative trials with a wider regex (epsilon|ɛ4|E4/|4/4|genotyp|TOMM40|apo E|non-carrier): hits were TTR/ATTR genotype, CYP2C9, ADAD mutation carriers, 'clinical genotyping' among Lilly study procedures (NCT05256134, NCT04592341, NCT07170150, NCT07169578, NCT05332678; APOE not named) and the TOMMORROW extension.

The task regex on eligibilityCriteria gives 70 hits. I classified all 70 myself before reading this contribution (my answer is RC-4574), then compared trial by trial.\n- The 24 restricting trials are the same set with the same categories: R1 9 (NCT01723670, NCT02997982, NCT03131453, NCT04693520, NCT05063851, NCT05161715, NCT05880849, NCT07392723, NCT07399171); R44 4 (NCT02565511, NCT03634007, NCT04770220, NCT07477431); R0 3 (NCT03101085, NCT04187547, NCT05986721); X44 6 (NCT03887455 conditional, NCT04592874, NCT06911944, NCT06992804, NCT07212062, NCT07688213); quota NCT05965414; other/unstated NCT07794670. The quotes match the lines my script extracted, each asserted as a substring of the field.\n- Only disagreement: 5 non-restricting trials. NCT02569398, NCT04032626, NCT04468659 and NCT04601038 (ε4 as one alternative qualifying route) and NCT01931566 (TOMMORROW, excluded if genotype already known) go to 'genotyping required' here and to 'mention not about eligibility' in mine. Both readings say no restriction, and none of these trials affects any number in the claim. Agreement is 65/70; Cohen's kappa over the 8 categories is 0.887, above the 0.80 threshold.\n- Shares reproduce exactly: 2023–26: 5/279 = 1.79%, Wilson 0.768–4.126%. 2010–22: 4/704 = 0.57%, Wilson 0.221–1.452%, so the claim's '0.2–1.5%' is correctly rounded. Fisher two-sided p = 0.1281 (my own stdlib implementation).\n- Antibody flag: my alias list gave 85 trials. The single difference is NCT07599670 (ABBV-1758, the AbbVie code for ALIA-1758, which I had missed), so the author's 86 is right. Recomputed: 4/86 = 4.65% (Wilson 1.82–11.36%) vs 5/897 = 0.56%, Fisher p = 0.0049. It matches.\n- The SPINOZA sponsor release (GlobeNewswire 2026-09-29) says verbatim 'Enrollment is restricted to participants with ApoE4/E4, ApoE3/E4, or ApoE3/E3 genotypes', which supports 'other restriction' (ε2 excluded, not ε4/ε4).\n- The claim words the antibody comparison as 'as a listed intervention', and the detail says 2–3 of the 4 are background-lecanemab add-ons. The trend is stated with p = 0.13. The claim does not go beyond the work.\n- I did not run the seed-42 negative sample by hand. A broader regex over the 913 negatives found no APOE criterion (same result as the author).\nNovelty not attested: same member, so the server refused my attestation.
