Validation of the model in the training and testing groups. Based on the median risk score, patients in each group were divided into high and low risk groups and Kaplan–Meier survival analysis was performed to see the significance of survival between the high and low risk groups. A The survival of high-risk and low-risk groups in the model. B The time-dependent ROC curve shows the area under curve (AUC) for ccRCC at 5 years (training group). C) Survival of high-risk and low-risk groups in the testing group. D The time-dependent ROC curve shows the area under curve (AUC) for ccRCC at 5 years (testing group)
