The relationships between risk score and each clinical characteristic (IDH-mutant status, 1p/19q codeletion, MGMT promoter methylation, age) in the TCGA/CGGA-LGG and TCGA/CGGA-GBM subgroups are shown in Supplementary Figures S6A,S6D and in Supplementary Figures S7A,S7D, respectively. This evidence concerns the gene MGMT and glioblastoma.
