Primary completion is the date the sponsor filed with the registry — their own projection, revised whenever they revise it, unless the row is marked actual.

How Schizophrenia is matched — 9 exact registry spellings

A study is on this page when its ClinicalTrials.gov record names one of these conditions exactly (letter case aside). Nothing is matched by substring or stem, so a longer condition that merely contains one of these words is a different page. The list was curated by hand and last measured 2026-08-19; a spelling filed by only one study was not curated, so the counts here are a floor rather than the registry's own total for the disease.
