Differential Gene Expression Analysis and GSEA for Risk Group. (A) Volcano map of differential gene expression between high- and low-risk groups among RS samples. (B) Heat map of DEGs between high- and low-risk groups in RS samples. (C) The mountain map of GSEA4 biological functions of RS samples is displayed. (D–G) GSEA indicated an extensive enrichment of RS in Oxidative Phosphorus (D), Electron Transport Chain Oxphos System in Mitochondria (E), the Citric Acid Tca Cycle and Respiratory Electron Transport (F) and Respiratory Electron Transport (G). GSEA, Gene Set Enrichment Analysis. The screening criteria for GSEA are adj. p—value < 0.05 and FDR < 0.25.
