Prognostic value of hypoxic risk in GC. A–C Kaplan–Meier curves for patients of high- and low-hypoxic risk groups in TCGA and GEO (GSE84437, GSE15459) databases. D–F Mortality rates of the high- and low-hypoxic risk groups in TCGA and GEO (GSE84437, GSE15459) databases. G–I Risk values are sorted and the dotted line in the middle divides patients into high- and low-risk groups (TCGA and GEO databases). The green dots are low-risk patients, and the red dots are high-risk patients. J–L Patient status distribution in the high- and low-hypoxic risk groups. The dot presents patient status ranked by the increasing risk score, where death is in red and alive is in green. The X axis is patient number and Y axis is survival time. M–O Heat maps showing six hypoxic gene expression profiles in high- and low-hypoxic risk groups from the TCGA and GEO databases
