Comprehensive molecular characterization and identification of prognostic signature in stomach adenocarcinoma on the basis of energy-metabolism-related genes

Figure 6 Internal validation of the 6-gene signature’s robustness in the internal validation set and entire The Cancer Genome Atlas cohort. A and B: Risk score, survival time, survival status and expression of the 6-gene signature in the internal validation set (A) and the entire The Cancer Genome Atlas (TCGA) cohort (B); C and D: Receiver operating characteristic (ROC) curve of the 6-gene signature for 1-year, 3-year and 5-year survival in the internal validation set (C) and the entire TCGA cohort (D); E and F: Kaplan-Meier survival analysis of PFS for high-risk or low-risk group patients in the internal validation set (E) and the entire TCGA cohort (F). AUC: Area under the curve; HR: Hazard ratio; CI: Confidence interval.
