About this index
Every entry links to a primary source — a peer-reviewed study, meta-analysis, or official reference — that we verified by reading it. Each note reports the study's real numbers and its limitations. None of it is medical advice or a recommendation, and we include null and conflicting findings on purpose. No entries are first-party; these are all independent sources.
How it's curated
Peer-reviewed studies, meta-analyses, and official references — each verified by reading the source, never a blog summary.
Each note reports what a study found — with its real numbers and its limitations. We surface the evidence; we don't give advice.
Null, conflicting, and limiting findings are included on purpose. Cherry-picking only the favorable studies would be its own kind of claim.
