Protocol: CT.gov Country Reporting Map

This protocol explodes eligible older closed interventional ClinicalTrials.gov studies into study-country involvements using named countries extracted from recorded locations. Primary outputs compare two-year no-results rates, ghost-protocol rates, and fully visible shares across countries with sizable eligible older study counts, with secondary contrasts among selected large countries. The aim is to expose named geographic transparency divides that country-count buckets cannot show. Because country labels come from recorded locations, the project measures country involvement rather than enrollment share, legal jurisdiction, or sponsor domicile.
