Average ± SD, sensitivity, specificity, PPV, and NPV of pretreatment rCBV_max and MD_min in patients with GBM demonstrating long (≥15 mo) survival and short (<15 mo) survival

	Long Survival (n = 30)	Short Survival (n = 28)	Cutoff	AUC	Sensitivity	Specificity	PPV	NPV
	Mean ± SD	Mean ± SD	Cutoff	AUC	Sensitivity	Specificity	PPV	NPV
rCBV_max	4.78 ± 1.30	9.90 ± 4.01^{^a}	5.79	0.93	0.89	0.90	0.89	0.90
MD_min (10⁻³mm²/s)	0.80 ± 0.17	0.75 ± 0.15	0.83	0.55	0.71	0.47	0.56	0.64

Note:—NPV indicates negative predictive value; PPV, positive predictive value; AUC, area under the curve.
