Figure 6. Evaluation of the predictive performance of the identified signature in the proneural subtype of GBM: (A) time-dependent ROC curves with corresponding AUCs at one and two years in training set (TCGA, $$ n = $$ 38); (B) time-dependent ROC curves with corresponding AUCs at one and two years in testing set (CGGA, $$ n = $$ 30); (C) KM curves for high-risk and low-risk patients in training set; and (D) KM curves for high-risk and low-risk patients in testing set. $$ P $$-values were calculated from the log-rank test. TCGA: The Cancer Genome Atlas. CGGA: Chinese Glioma Genome Atlas. ROC: receiver operating characteristic. GBM: glioblastoma multiforme. KM: Kaplan-Meier.
