Protocol: CT.gov Cardiovascular Hiddenness

This protocol isolates the cardiovascular portfolio from the March 29, 2026 ClinicalTrials.gov full-registry snapshot using a keyword-based family map applied to eligible older closed interventional studies. Primary outputs compare two-year no-results rates, ghost-protocol rates, sponsor-class contrasts, phase structure, and named lead sponsors by unresolved stock within the family. The aim is to treat major therapeutic areas as standalone evidence systems rather than as subpanels inside a general registry atlas. Because the family map is keyword-based and single-label, the project is descriptive and can compress multi-topic trials into one dominant family.
