Figure 6. Enrichment analysis and functional annotation. (A) Differentially expressed genes between high- and low-risk groups (FDR <0.05, log2 (FC) > 1). (B) The GSVA analysis demonstrates the enrichment of hallmark gene sets within various risk groups. (C) Bar graphs are commonly utilized to show GO enrichment analysis. (D) The GSEA enrichment analysis method revealed notable variations in pathways between groups classified as high risk and low risk.
