Receiver operating characteristic (ROC) curve analysis

Measures	AUC	Threshold	Sensitivity (%)	Specificity (%)	p value
ADC (10^-3 mm²/s)	0.55	1.12	62.5	62.5	0.29
f	0.71	0.22	62.5	75.0	0.008^*
D (10^-3 m²/s)	0.74	0.80	56.2	93.7	0.003^*
D^* (10^-3 m²/s)	0.53	43.15	62.5	62.5	0.35
[f , D]	0.76	[0.21,0.35]	62.5	81.2	0.0009^*

indicate that the AUC is statistically greater than 0.5 (p value<0.05)
