Lysophospholipids
lipidLysophospholipids are potent inflammatory mediators generated by phospholipase A2 that recruit leukocytes, activate platelets, and destabilize plaques.

Type I vs Type II discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I65
C — confounder / Type-II86

Specificity differential (R−C)-21.1
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
