Strict Repeaters Dashboard

Strict-core repeaters show that the regulated-looking backlog remains spread across government-linked, academic, and industry sponsors

NCI leads the named strict-core table, Mayo and MD Anderson remain close behind, OTHER and INDUSTRY stay close on class stock, and oncology dominates the strict-core condition table.

NCI leads, but Mayo, MD Anderson, Sanofi, and other institutions remain close enough to show a broad repeater field.
The strict-core story is still distributed.
