Representative results of GO and KEGG enrichment analysis in the training and validation sets. (A, B) GO analysis showed that many immune-related biological processes were enriched in the training (A) and validation (B) cohorts. (C, D) KEGG analysis showed that some immune-related pathways and cancer proliferation pathways were enriched in the training (C) and validation (D) cohorts. The gene ratio refers to the ratio of DEGs between high- and low-risk groups to the set of genes for each GO or KEGG pathway.
