Figure 4.Kaplan–Meier and ROC curves for risk score in the training set, test set and subgroups. (A) The log-rank test p in training set was 3.11e-13, HR = 13.82. (B) The log-rank test p in test set was 3.741e-7, HR = 8.249. (C) The 1-year AUC of risk score in the training set was 0.9225; the 3-year AUC of risk score in the training set was 0.9167. (D) The 1-year AUC of risk score in the training set was 0.8900; the 3-year AUC of risk score in the training set was 0.7601. (E–J) The subgroups Kaplan–Meier analysis of risk score.
