Sponsor Debt Project

Boehringer 15.2k
NCI 14.0k

Project

This page shifts the sponsor story from counts to accumulated time. It asks which named sponsors hold the deepest stock of unresolved overdue years after the reporting deadline has already passed.

Chronic silence is not just how many studies remain overdue. It is how many overdue years large sponsor portfolios continue to hold.

The sponsor debt table is led by large industry portfolios, with NCI prominent among public sponsors.
This is chronic silence measured as time rather than counts alone.
