Figure 4. (A–C) Prognostic differences between the high-risk and low-risk groups were investigated in the training set, validation set, and the entire dataset. High risk was found to indicate poor prognosis in all three datasets (p<0.001). (D–F) In the training set, validation set and the entire set, the AUC values obtained by the prognostic model to predict the accuracy of the 5-year survival rate of patients were 0.741, 0.798 and 0.747, respectively.
