Companies reaching this through an API (1)

These companies publish an API, specification or operation carrying “Clinical Trials” but do not classify their business under it. Listed unranked and kept out of the count above, because one tagged operation is not a statement about what a company does.

Facet averages, against the whole catalog

Facet	This cohort	Catalog	Difference	Scored
Contract Governance	3.7	6.5	-2.8	288
Discoverability	58.1	61	-2.9	288

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
