Prognostic value and external validation of hypoxia genes. A K–M curves of patients in high- (red) and low-risk groups (blue) of ICGC. B K–M curves of patients in high- (red) and low-risk groups (blue) of TCGA. C, D Sorting patients according to risk score in ICGC and TCGA respectively. E, F Association between survival time and risk score in ICGC and TCGA separately. G, H Relationship between risk score and the expression of ENO1, TPI1 and UGP2. I, J The mortality rate in high- and low-risk groups of ICGC and TCGA
