Univariate survival analyses based on enrichment scores of T‐cell subsets. A, Heat map of enrichment scores of T‐cell subsets calculated using xCell tool in 97 HPV‐positive HNSCCs and 423 HPV‐negative HNSCCs obtained from TCGA database. B and C, Kaplan‐Meier survival curves based on enrichment scores of CD4⁺ T cells, Th1 cells, Th2 cells, Tregs, CD8⁺ T cells, CD8⁺ T_Ns, CD8⁺ T_CMs, and CD8⁺ T_EMs. B, Survival curves for DFS. C, Survival curves for OS. DFS, disease‐free survival; HNSCC, head neck squamous cell carcinoma; HPV, human papillomavirus; OS, overall survival; TCGA, The Cancer Genome Atlas; T_CMs, central memory T cells; T_EMs, effector memory T cells; T_Ns, naïve T cells; Tregs, regulatory T cells
