Consensus clustering of GBM samples. A Color-coded heatmaps corresponding to the consensus matrices for k = 2 to k = 4. B PCA of two groups (k = 2) based on gene expression data in TCGA. C Kaplan–Meier curves survival based on the two GBM immune subtypes in the TCGA cohort. D PCA of two groups (k = 2) based on gene expression data in CGGA. E Kaplan–Meier curves survival based on the two GBM immune subtypes in the CGGA cohort
