Figure 4. The results of Gene Ontology (GO) and KEGG pathway analyses. (A) Volcano plot of DEGs grouped as high- and low-risk using the Cox regression model. (B) Box plots showing the functional similarity analysis of the top 10 genes. (C) Bar plots displaying the results of GO and KEGG pathway enrichment analyses of the DEGs. (D) Pathway map for the Neuroactive ligand-receptor interaction pathway, with color mapping from green to red indicating increasing logFC values. (E) Correlation heatmap for the top 10 functionally similar genes.
