The ROC curve of clinical features, radiomic, clinical features + radiomic model in the validation cohort.

Model	AUC	95% CI	Sensitivity	Specificity
Clinical model	0.779	0.564 - 0.921	0.600	0.929
LR-radiomic	0.914	0.776 - 0.998	0.700	0.929
SVM-radiomic	0.929	0.746 - 0.993	0.900	0.857
Combined 1 (clinical+LR-radiomic)	0.957	0.787 - 0.999	1.000	0.857
Combined 2 (clinical+SVM-radiomic)	0.943	0.766 - 0.997	0.846	0.929

AUC, area under curve; LR, logistic regression; 95% CI, 95% confidence interval; SVM, support vector machine.
