Type I vs Type II discrimination

ScoresLow-confidence (proxy)
R — rupture / Type-I
35
C — confounder / Type-II
53
A — assay feasibility
66
E — evidence strength
21

Specificity differential (R−C)-18.3
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
