Correlation between the risk score and overall survival of LIHC patients in the training and validation set. A The distribution of risk scores in the training set. B The distribution of risk scores in the internal validation set. C The distribution of risk scores in the external validation set. D The survival status of patients in the training set. E The survival status of patients in the internal validation set. F The survival status of patients in the external validation set. G Heat map of 3 genes expression in the training set. H Heat map of 3 genes expression in the internal validation set. I Heat map of 3 genes expression in the external validation set. J Kaplan–Meier curves of survival in training set. K Kaplan–Meier curves of survival in internal validation set. L Kaplan–Meier curves of survival in external validation set. M Time-dependent ROC curve of the risk score model for predicting 1 years in training set. N Time-dependent ROC curve of the risk score model for predicting 1 years in internal validation set. O Time-dependent ROC curve of the risk score model for predicting 1 years in external validation set
