## Methodology

This report was captured automatically on 2026-06-16 (methodology version 1) and is never edited afterward, so the numbers are reproducible. Recruiting counts reflect trials open at capture time; "total ever registered" counts every Parkinson's trial in the universal registry mirror regardless of status, and is not subject to survivorship bias. A trial running in several countries is counted once per country.
