Project
This page steps back from named entities and asks how the endpoint-only gap sorts across the sponsor classes used in the CT.gov registry.
The class view matters because high-stock classes and high-rate classes are not the same thing in this endpoint-only map.
A standalone E156 project on which sponsor classes most often omit endpoint text while the broad study narrative remains on older CT.gov records.
Across The Series
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.
