Bars are counts of papers or trials; a longer bar means more studies, not better results. Study counts auto-counted from PubMed tags and ClinicalTrials.gov in the Ellum research database, as of October 6, 2026 (not reviewed; a paper can carry more than one tag). Papers PubMed tags as about people: includes reviews and case reports; not randomized trials. All bars share one scale. Each count is for that part alone.
