Evaluation of the SVM radiomics model in the training and validation cohorts.

Cohort	AUC (95% CI)	THRE	Accuracy	Sensitivity	Specificity	PPV	NPV	Brier score
Training	0.796 (0.701–0.891)	0.483	0.764	0.69	0.83	0.784	0.75	0.187
Validation	0.739 (0.63–0.847)	0.374	0.708	0.881	0.553	0.638	0.839	0.216

AUC, area under the receiver operating characteristic curve; CI, confidence interval; PPV, positive predictive value; NPV, negative predictive value; THRE, threshold.
