Figure 6. Functional enrichment analysis of the differential expressed genes (DEGs) in the low- and high-risk group. (A) Volcano diagram shows the DEGs in the low- and high-risk group with the threshold set at |Fold change| ≥ 1 and p-value < 0.05. (B) GSVA illustrates the KEGG terms of each CM patient in the low- and high-risk group. (C) GO enrichment analysis shows the top 15 biological processes (BP) of the DEGs. (D) KEGG enrichment analysis reveals the top 15 enrichment signaling approaches of the DEGs.
