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

Figure 3 Construction of the ferroptosis-related genes prognostic index and its value in predicting gastric cancer. A: Overlap of differentially expressed genes and prognostic genes; B: Forest plot showing the multivariate Cox model results for the Co-regulated differentially expressed genes; C and D: LASSO analysis of related genes; E: Expression of hub genes in gastric cancer (GC) and normal tissues (The Cancer Genome Atlas); F: Expression of hub genes in GC and normal tissues (GSE99553); G: Receiver operating characteristic curves (ROC) of hub genes for predicting GC (GSE99553); H: H: ROC curves of hub genes combined detection for predicting GC (GSE99553); I: ROC curve of hub genes for predicting H. pylori infection-related GC (GSE99553); J: ROC curve of hub genes combined detection for predicting H. pylori infection-related GC (GSE99553). ^aP < 0.05, ^bP < 0.01, ^cP < 0.001.
