Sponsor Watchlist Dashboard

Named-sponsor watchlists show that excess hiddenness is carried by a mixed field of hospital systems, universities, and large drug companies

AP-HP leads on adjusted excess no-results stock, Sanofi is the clearest large industry repeater, Cairo University remains prominent on both no-results and ghost excess, and NCI tops the strict-core missing-results table.

AP-HP, Sanofi, and Cairo University rise to the top on adjusted excess no-results stock, while Sanofi also stands out on ghost excess and NCI leads the strict-core carryover.

The upper tier mixes public hospital systems, universities, and major drug companies.
The adjusted sponsor table therefore resists a single-sector explanation.

Sanofi and Cairo University stand out sharply once the target changes from missing results to ghost protocols.
That is a more severe silence state than overdue results alone.

NCI, Mayo, MD Anderson, and Sanofi show that the strict-core backlog is spread across government-linked, academic, and industry sponsors.
The regulated-looking subset does not collapse to one institutional archetype either.
