Project
This page narrows the series from sponsor classes to named sponsors. It keeps the study-mix adjustment and asks which institutions still remain worse than expected afterward.
The sponsor backlog does not collapse into one sector. It stays distributed across hospitals, universities, and industry portfolios.
A standalone E156 project on which named sponsors still carry the largest excess hiddenness stock after visible study mix is held more constant.

The split projects are meant to be read together because each isolates a different dimension of registry opacity rather than forcing every question into one leaderboard.
