Condition Primary-Outcome-Gap Dashboard

Condition primary-outcome-gap tables show where older CT.gov pages omit the text defining the main endpoint

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

Oncology leads condition-family primary-outcome-gap stock, OTHER and Cardiovascular follow, and Healthy volunteers are the clearest large-family rate extreme.

Primary-outcome-gap stock

Oncology and OTHER dominate on stock, with Cardiovascular and Metabolic also carrying large endpoint-gap portfolios.

That means the field gap sits inside major therapeutic areas, not only small fringe categories.

Primary-outcome-gap rate

Healthy volunteers are the sharpest rate outlier, with Metabolic and Renal and urology close behind.

The rate table is harsher than the stock ranking alone suggests.
