No cancer outcome differs significantly between GLP-1 receptor agonists and placebo after correction in these trials: reports of any malignant neoplasm (1.03, 95% CI 0.97 to 1.09, q = 0.48), of the cancers linked to excess body fat (1.09, 0.99 to 1.19, q = 0.20) and of pancreatic cancer (0.99, 0.75 to 1.32, q = 0.95). Thyroid cancer reports are nominally higher (67 against 32; 1.61, 1.02 to 2.55, p = 0.042; Peto's odds ratio 1.61, 1.07 to 2.41) but not after correction (q = 0.14), so the trials neither confirm nor exclude an increase.

It would be wrong if A rerun gives q below 0.05 for any of these cancer outcomes.

How important it is

Being rated under edition 4 of the rubric: 0 of 4 ratings are in. Its score, and why each rater gave theirs, show once all 4 are, so no rater sees another’s first.

Importance is how much what the claim establishes matters to humanity: how much it would matter if it holds, beyond what was already known, weighed by how strongly its evidence shows that it does, from 0, changing little that matters, to 100, civilization-level importance on overwhelming evidence. It isn’t a verdict on whether the claim is true: its checks and statuses say that. How importance is judged

   Computational reproduction

   All nine assigned claims reproduced computationally: 146 of 146 declared evidence references match the fresh outputs within stated tolerances. All eight result JSON objects are exactly equal after parsing.

   The three submitted Python scripts ran unchanged through sh code/run in a fresh offline container with Python 3.12, numpy 2.5.3 and scipy 1.18.1, one CPU, 1 GiB memory, no host mounts, all capabilities dropped and no-new-privileges. Only code, env and data were supplied; no submitted results were copied. Execution completed successfully in 7.73 seconds. All 366 separately served data files were downloaded and their sizes and SHA-256 digests verified before execution. The input holds 539 public registry records.

   This is computational reproduction from supplied records, coding and source-resolution tables, not an independent re-extraction of every report or clinical endorsement. The revision retains the registered outputs and adds clustered variances, within-arm overlap sensitivities, comparisons incorporating uncertainty in both estimates, and analyses by recording window. Reproducing those calculations does not turn report counts into distinct participant counts or establish equivalence between observational and trial estimands. These limitations are described in the paper.

   All job integrity categories were empty. Screening found public registry records and aggregate trial results, code, bibliographic data, and cited short extracts or factual paraphrases. Contact fields are publicly posted professional trial contact roles, not private participant contact details. No identifiable private participant records, credentials, mass-harm-enabling content, or identified unauthorized substantial copy was found. Hazard: none. This evidence includes computed outputs and checks, not the source registry records or article copies.
