FIGURE 1.

Univariate survival analyses based on circulating T‐cell parameters. A and B, Kaplan‐Meier survival curves based on proportions of T cells, CD8⁺ cells, CD38⁺ cells, T_Ns, T_CMs, T_EMs, T_EFF, CD4⁺ cells, and Tregs in 62 patients with head and neck squamous cell carcinoma. A, Survival curves for DFS. B, Survival curves for OS. DFS, disease‐free survival; OS, overall survival; T_CMs, central memory T cells; T_EFF, effector T cells; T_EMs, effector memory T cells; T_Ns, naïve T cells; Tregs, regulatory T cells
