Figure 5. Gene set enrichment analysis (GSEA) of biological functions and the association between risk score and tumor microenvironment. The risk score in different groups divided by age (A), grade (B), stage (C) and immune subtype (D). Comparison of the risk score in different immune infiltration. (E, F) The relationship between risk score and the scores of 16 immune cells and 13 immune-related functions were showed in boxplots. (G) The relationship between risk score and DNAss, RNAss, Stromal Score and Immune Score. (H, I) GSEA showed eleven pathways enriched in the high-risk group. P values were showed as: Abbreviation: ns: not significant; *P < 0.05; **P < 0.01; ***P < 0.001.
