Predictive model using four ferroptosis-related genes accurately predicts gastric cancer prognosis

Figure 4 The ferroptosis-related genes prognostic index independently predicts gastric cancer patient survival. A: Risk score distribution and patient survival in the low- and high-risk groups of the cancer genome atlas of stomach adenocarcinoma (TCGA-STAD); B: Risk score distribution and patient survival in the low- and high-risk groups of GSE84426 cohorts; C: K–M survival analysis of the TCGA-STAD; D: K–M survival analysis of GSE84426 cohorts; E: Areas under the curve (AUC) of the time-dependent receiver operating characteristic curves (ROC) for the ferroptosis-related gene prognostic index in the TCGA-STAD; F: AUC of the time-dependent ROC curve for the GSE84426 cohorts. FPR: False positive rate; HR: Hazard ratio; TPR: True positive rate.
