(A). Receiver operating characteristic curves of compression stiffening rate and elasticity for high solid stress (A) and substantial collagen content (B). Compression stiffening rate has high performance in diagnosing elevated solid stress (AUC: 0.86 ± 0.08), in contrast to elasticity (AUC: 0.63 ± 0.12) (A). Elasticity has high performance in diagnosing collagen content (AUC: 0.86 ± 0.08), in contrast to compression stiffening rate (AUC: 0.59 ± 0.12) (B).
