Protocol: CT.gov Sponsor Ancient Backlog

This protocol isolates the oldest unresolved slice of the sponsor backlog. Ancient backlog is defined as an eligible older closed interventional study with no posted results and at least ten overdue years beyond the two-year mark. Primary outputs rank named sponsors with at least 100 older studies by ancient-backlog stock, ancient-backlog rate, and overdue-years depth.
