Coverage and gaps

This is a growing index of selected public sources. Shared authors, copied pages and overlapping cohorts do not count as independent corroboration. Date, unit, taxon, denominator and endpoint gaps remain visible in the reports.

Human-origin judgments rely on attribution and source evidence; no reliable AI detector is claimed. This library republishes original limited summaries and attribution, with no publisher full text or media.
