Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I20
C — non-Type-I46
A — assay feasibility42
E — evidence strength16
T1DI (composite)3
Specificity differential (R−C)-26.1
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.
