Magellan grades every product it lists against the published literature. That work leaves behind a dataset. These reports read it sideways — as a description of the longevity market rather than of any single product — and publish the method, the code and the raw rows so the numbers can be checked rather than trusted.
130 graded longevity products, 2,353 unique PubMed-indexed citations and 314 structured study write-ups, analysed together. 11 products (8.5%) earn a Strong evidence grade; 31.8% of the citation corpus is randomized; 42.4% of the randomized write-ups report at least one null result; and the correlation between a product’s Amazon star rating and its evidence grade is 0.18.
The evidence-gap analysis is versioned and will be re-run as the catalogue and its citation lists change; each re-run gets a new version number and a dated changelog rather than a silent edit. Corrections to any figure are welcome — the fastest route is to point at the row in the CSV that you think is wrong.
