Protocol: CT.gov Evidence Visibility Gap

This protocol evaluates evidence visibility states inside eligible older closed interventional studies from the March 29, 2026 ClinicalTrials.gov full-registry snapshot. Each record is classified into one of four states: results plus publication, results without publication, publication without results, or neither. The primary estimand is the ghost-protocol rate, defined as missing posted results plus missing linked publication among eligible older studies. Secondary outputs compare full visibility and ghost-protocol rates across sponsor classes and phases so partial visibility is not mistaken for full disclosure.
