(1) Europe PMC REST: query '\"NCTxxxxxxxx\" AND (SRC:MED OR SRC:PPR)' (full-text index), one per ID (hits: 0 to 20 per ID; relevant hits are listed above). (2) The ClinicalTrials.gov referencesModule of each record: DERIVED refs led to PMIDs 41173838, 42527728, 42489967, 40424097, 40433895, 42428158, 41856444/40961133, 41174221, 42617697 and 34446377. (3) One web search per NCT: WebSearch '\"NCTxxxxxxxx\" + short topic keywords'. I ran 6 myself (NCT05297019, NCT04608448, NCT04110028, NCT05510375, NCT07799103, NCT06411366) and a helper agent ran the other 20. The web searches found the earlier preprints for NCT04946383 and NCT04361617 and the COSMOS paper for NCT05510375; preprint dates are from Crossref (posted dates). (4) Extra Europe PMC topic queries, and the full texts of PMC13577923, PMC12618261, PMC12181487, PMC13601483 and PMC10929829 grepped for clock results.\n\nMATCHING NOTES / UNCERTAINTIES (a checker should look here first).\n- TranslAGE (PMID 42629466) is the only report for three industry trials. NCT06411366 is named in its methods. NCT05297019 is matched by protocol number SM-TD-001 and the New Jersey HBOT site, both of which appear in the paper and in the registry. NCT05297097 is matched only by the product name 'TruLacta supplement' (registry: 'Trulacta breastmilk supplement'); no NCT or protocol ID is given in the paper.\n- NCT05678426: I could not retrieve the preprint's full text (the Europe PMC and bioRxiv pages were blocked), so its numeric clock values are not verified. Excluding it gives (b) 12/26.\n- NCT05510375: the Nature Medicine COSMOS paper is described as the 'prespecified ancillary study' on epigenetic clocks. I did not see its NCT citation (the paper is not in PMC). PMID 41217671 (2025-11-11) gives pooled COSMOS clock changes but not the registered intervention effect, so it is not counted as the first report.\n- NCT06534450 and NCT04361617: the first reports are preprints I did not open (medRxiv returned 403). Their journal versions contain the clock results.\n- NCT06234436 and NCT05488951: I judged these from abstracts only. A clock result in the full text would move them to (b).\n- The web hits PMID 37254221 (trial NCT04981821) and PMC10919904 (a rodent study) are not these trials.\n\nPRIOR ART re-run 2026-09-30: a Europe PMC query ('(epigenetic clock OR epigenetic age OR DunedinPACE OR GrimAge) AND (ClinicalTrials.gov OR trial registry) AND (results reporting OR unpublished OR publication rate OR non-publication OR reporting rate)', 40 hits) and a WebSearch ('registered clinical trials epigenetic clock outcome ClinicalTrials.gov proportion reported results publication analysis') found no registry-to-publication audit for clock outcomes. The task's prior-art statement still holds.\n\nREPRODUCTION. analyse.py (Python 3.14, standard library only, no randomness) reads ctgov.json and table_manual.json and writes table.csv and results.json. sha256: analyse.py de930eec451a543fa1a98df197e9b72033ccf11ac9558ba4e23549adf21bb11c; table_manual.json 7cce95b30467d699ebf8ebb5e72b589edf80a567cc4834460b6f28467009c097; table.csv 05d8cdf9051838fe1694b322ac0f58c81997e2face1a54af59c58184da82ec19; results.json 9969a7e6add77ac04082ce2b6c3ae1b8af21fe7147c711caa5ced8214c246717; epmc_log.json 4b0c165b4fd31aaef4c7766e58c6c260bbba8890af7ad2f1284135ef7c58f273.

Rebuilding the Kaplan-Meier curve from the submitted 13 event and 13 censor times gave point median 1209 days; the log-S Greenwood lower band first crossed 0.5 at 1035 days and the upper band remained 0.669684 at the last event, so the upper confidence limit was not reached.
