Model	Sensitivity	Specificity	Accuracy	Recall	Precision	AUC (95%CI)
Nomogram	0.867	0.909	0.927	1.000	0.921	0.950 (0.908-0.992)
Decision tree	0.836	0.864	0.951	0.994	0.955	0.882 (0.797-0.968)
Random forest	0.984	0.727	0.893	1.000	0.889	0.934 (0.883-0.985)

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