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

GlaxoSmithKline leads sponsor primary-outcome-gap stock, Boehringer Ingelheim and Sanofi remain close behind, Ranbaxy and Mylan are extreme on rate, and NIH edges Industry on sponsor-class rate.

GlaxoSmithKline, Boehringer Ingelheim, Sanofi, Pfizer, and AstraZeneca dominate the stock table.
The largest primary-outcome text gaps therefore sit in major mature sponsor portfolios rather than obscure corners of the registry.
