Sponsor Detailed-Description-Gap Dashboard

Sponsor detailed-description-gap tables show where older CT.gov pages lose the broad study narrative

GlaxoSmithKline leads sponsor detailed-description-gap stock, Boehringer Ingelheim and Pfizer remain close behind, and Novo Nordisk plus Boehringer are extreme on rate while Industry dominates the class table.

GlaxoSmithKline leads sponsor detailed-description-gap stock, Boehringer Ingelheim and Pfizer follow, and Novo Nordisk is the sharpest large-sponsor rate outlier.

Class rate

Detailed-description-gap stock

GlaxoSmithKline, Boehringer Ingelheim, Pfizer, and Roche dominate the stock table.

Large mature sponsor portfolios therefore drive much of the missing broad narrative layer.

Detailed-description-gap rate

Novo Nordisk, Boehringer Ingelheim, Roche, and Mylan are the sharpest rate outliers.

Stock and rate identify overlapping but not identical sponsor repeaters.

Sponsor-class rate

Industry stands far above the major non-industry classes on detailed-description rate.

That class table shows the broad narrative field is especially thin in industry portfolios.
