Time-dependent ROC curves of the three different models in the training and validation cohorts. (a) The time-dependent ROC curves based on Rad-score in both the training and cohorts. AUCs at 1-, 3-, and 5-year RFS were calculated from time-dependent ROC curves to evaluate the prognostic accuracy. (b) The time-dependent ROC curves based on NLR and tumor size. (c) The time-dependent ROC curves based on clinical-radiomics model
