The prognostic value of risk score in OS. The K-M curves of high-risk score and low-risk score group in the whole grade (A, B), grade 2 (C, D), grade 3 (E, F), grade 4 (G, H), lower-grade (I, J) and high grade (K, L) gliomas. (A, C, E, G, I, K) from CGGA database. (B, D, F, H, J. L) from TCGA database. The time-dependent ROC analysis of the sensitivity and specificity of the survival for the five-genes signature in CGGA (M) and TCGA (N).

OS, overall survival; K-M, Kaplan-Meier; CGGA, the Chinses Glioma Genome Atlas; TCGA, The Cancer Genome Atlas; ROC, receiver operating characteristic.
