Model	Sensitivity	Specificity	Accuracy	Recall	Precision	AUC (95%CI)
Nomogram	0.745	0.966	0.936	0.987	0.946	0.922 (0.883-0.961)
Decision tree	0.833	0.862	0.951	0.994	0.955	0.919 (0.863-0.975)
Random forest	1.000	1.000	0.951	0.994	0.955	1.000 (1.000-1.000)

AUC: Area under the receiver operating characteristic curve; CI: Confidence interval.
