System performance evaluation.

	Logistic	Probit
AUC	0.84 (0.74–0.94)	0.84 (0.74–0.94)
Accuracy	0.78	0.78
Brier (scaled)	0.34	0.39
Nagelkerke	0.36	0.28
HL	0.29	Na
(P)	0.27 (0.60)	0.32 (0.57)
NPV-TV50	0.83	0.84
NPV-TV25	0.90	0.93
AIC	66.70	68.64

AUC: area under the receiver operating characteristic curve; HL: Hosmer-Lemeshow test; NPV: negative predictive value; (P): a chi-square goodness-of-fit test; P value of >0.05 indicates lack of statistical difference between predictive risk and the observed outcome.
