Table 4. Mean areas under the receiver operating characteristic curves (AUCs) of the clinical, radiomics and combined models calculated from 100 iterations of an internal validation process.

Model	Mean AUC±SE	Median AUC (Q1, Q3)
Clinical RF model	0.907±0.036	0.912 (0.880, 0.933)
Radiomics RF model	0.921±0.031	0.922 (0.903, 0.940)
Combined LR model	0.934±0.030	0.939 (0.918, 0.951)

RF, Random Forest; LR, logistic regression; SE, standard error.
