Protocol: CT.gov Phase Reporting Gap

This protocol groups interventional ClinicalTrials.gov studies by reported phase using the March 29, 2026 full-registry snapshot. The main comparison set includes 441,191 interventional studies, with 290,524 closed interventional studies and 249,507 eligible older studies driving the primary estimand. Primary outputs compare eligible 2-year no-results rates and unresolved missing-results stock across phase labels, including the large NA bucket. The aim is to show how reporting silence changes across the development pathway rather than treating sponsor class as the only structural explanation.
