Figure 7. Evaluation of the predictive performance of the identified signature in LGG: (A) time-dependent ROC curves with corresponding AUCs at one, two, and three years in training set (TCGA, $$ n = $$ 525); (B) time-dependent ROC curves with corresponding AUCs at one, two, and three years in testing set (CGGA, $$ n = $$ 172); (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. LGG: lower-grade gliomas. KM: Kaplan-Meier.
