Prognostic nomogram model for overall survival in patients with hepatocellular carcinoma

Figure 3 The generalization ability of the nomogram model. A: The time-dependent concordance index of the nomogram model; B: The time-dependent area under the receiver operating characteristic curve of the nomogram model; C: The 1-year, 3-year and 5-year receiver operating characteristic curves for the nomogram model in the training set; D: The 1-year, 3-year and 5-year receiver operating characteristic curves for nomogram model in the validation set. AUC: Area under the receiver operating characteristic curve.
