Table 3. Performance measures of the models in the testing set.

	Accuracy (%)	Sensitivity (%)	Specificity (%)
Clinical RF model	83.8 (62/74)	81.1 (30/37)	86.5 (32/37)
Radiomics RF model	91.9 (68/74)	91.9 (34/37)	91.9 (34/37)
Combined LR model	94.6 (70/74)	97.3 (36/37)	91.9 (34/37)

Data in parentheses are proportions of lesions that were correctly classified. The performance measures of the models were calculated based on the maximal Youden index of the receiver operating characteristic curve. RF, Random Forest; LR, logistic regression.
