Type I vs non-Type I discrimination

ScoresLow-confidence (proxy)
R — rupture / Type-I
71
C — non-Type-I
77
A — assay feasibility
40
E — evidence strength
35
T1DI (composite)
7
Specificity differential (R−C)-6.3
Non-Type-I axis panel
Does this marker also move in each non-Type-I setting? mag 0–3; higher means less Type-I-specific. n/a = no evidence retrieved, which is not the same as no change.
No non-Type-I axis evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
