Condition Narrative-Gap Dashboard

Condition narrative-gap tables show where older CT.gov pages stay stripped of both core descriptive fields

OTHER and Oncology dominate condition-family narrative-gap stock, Cardiovascular remains large on count, and Healthy volunteers are far harsher on rate than the major named disease families.

OTHER and Oncology dominate on count, with Cardiovascular and Healthy volunteers still large enough to matter immediately.
The condition-family stock table shows that narrative gaps are not limited to fringe therapeutic areas.

Healthy volunteers are the sharpest rate outlier, with Metabolic and Renal and urology also unusually text-thin.
That rate pattern is harsher than the count ranking alone suggests.
