Fig. 3From: PI3K pathway mutation predicts an activated immune microenvironment and better immunotherapeutic efficacy in head and neck squamous cell carcinomaFunctional enrichment analysis. A Ten GO, KEGG, and Hallmark pathways enriched by GSVA analysis in the PI3K pathway mutation and wild groups, respectively. B, C GSEA analysis showed the top five pathways enriched in the PI3K pathway mutation group (B) and the top five pathways enriched in the wild group (C).
