Figure 3. Analysis of OS and DFS prognostic risk models in training group ccRCC patients. (A) Kaplan-Meier survival curve analysis of OS in the high-risk (red line) and low-risk (green line) ccRCC patients in the training group. (B) Kaplan-Meier survival curve analysis of disease-free survival (DFS) in the high-risk (red line) and low-risk (green line) ccRCC patients. (C) Time-dependent ROC curves show area under curve (AUC) values at 3-year (blue) and 5-year (red) OS in the training group ccRCC patients. (D) Time-dependent ROC curves show AUC values at 3-year (blue) and 5-year (red) DFS in the training group ccRCC patients.
