Country-linked stock and rate diverge again here: the United States dominates on net count, while Slovakia, Romania, and Poland are harsher on asymmetry rate.
Which country-linked CT.gov portfolios show the biggest imbalance between missing detailed descriptions and missing primary-outcome-only text in older records? We analysed 249,507 eligible older closed interventional studies from the March 29, 2026 full-registry snapshot and exploded country links. We compared description-only gaps against primary-only gaps and defined net text asymmetry as description-only minus primary-only counts and rates. The United States led the country-linked text-asymmetry table at 9,667 net description-only gaps, followed by Germany at 3,909, Spain at 3,571, and France at 3,442. Slovakia had the highest large-country asymmetry rate at 40.9 percentage points, while Romania reached 39.3 points and Poland 36.6 points. Country-linked text asymmetry shows where the broad study narrative disappears much more often than the endpoint sentence across national registry portfolios. It separates portfolios where the larger study narrative disappears while the endpoint line survives. Country-linked rows are non-exclusive because multinational studies can contribute to more than one national portfolio in registry link tables.
