In 5 placebo-controlled comparisons from 3 cluster-randomized trials (MORDOR in Niger, Malawi and Tanzania; AVENIR in Niger; CHAT in Burkina Faso), twice-yearly mass azithromycin to every child 1 to 59 months old lowered mortality among children 1 to 59 months by 14.1% (rate ratio 0.859, 95% CI 0.797 to 0.926; Holm-corrected p = 0.015; I² = 0%), and the reduction held with a common-effect model (0.859, 0.813 to 0.908) and with any one comparison left out (largest p = 0.044).

It would be wrong if A re-run on the bundle's data gives a 95% CI for the pooled rate ratio that includes 1, or a leave-one-out estimate with p of 0.05 or more; or a re-extraction from the trials' reports moves the pooled rate ratio by more than 0.02.

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 seven assigned computational claims reproduced. All 61 declared evidence references match the independently regenerated outputs within their stated tolerances. The ten result JSON objects are also exactly equal after parsing.

   The submitted environment was built from its pinned rocker/r-ver 4.6.1 digest and dated package source; the build verified metafor 5.2.1 and jsonlite 2.0.0. The two R scripts ran unchanged via sh code/run in a fresh container with no network, no host mounts, all capabilities dropped, one CPU and 1 GiB memory. Only code, env and data were copied in; no submitted results were supplied. The run completed successfully in approximately 1.5 seconds, below five minutes.

   This attests computational reproducibility from the supplied extraction tables, not independent re-extraction of every source or validation of every clinical interpretation. In particular, a non-significant time slope does not establish unchanged effects, and comparing one strategy's point estimate with another strategy's interval is not a direct test of strategy differences. Those are interpretation questions for methodological review and do not change the successful numerical reproduction.

   The job's integrity checks were empty across all categories; no outstanding deterministic warning was supplied. The hazard screen found aggregate public trial facts, bibliographic metadata, extraction decisions, code and derived results, with no identified private participant data, credentials, weapons-enabling content or identifiable unauthorized substantial source copy. Verdict: none. Evidence contains generated outputs and the comparison report, not source articles or the sealed bundle.
