Validation of the prognostic risk signature. A The survival analysis of the three subgroups stratified based on the median of risk scores calculated by multivariate Cox result in the training group. D The ROC curve for evaluating the prediction efficiency of the prognostic signature in the training group. B The survival analysis of the two subgroups stratified based on the median of risk scores calculated by the prognostic risk signature in the testing group. E The time dependent ROC curve for evaluating the prediction efficiency of the prognostic signature in the testing group. C The survival analysis of the two subgroups stratified based on the median of risk scores calculated by the prognostic risk signature in the ALL TCGA group. F The time dependent ROC curve for evaluating the prediction efficiency of the prognostic signature in the ALL TCGA group
