Figure 2. Association between high Treg- and high PD-L1⁺ myeloid cell rates in cervical lymph nodes.

Treg and PD-L1⁺ myeloid cell rates in non-tumor regions of all cervical lymph nodes were significantly correlated. The overall P value was calculated with One-way ANOVA Kruskal-Wallis test. For testing of selected groups, Dunn's post hoc test was used. **P = 0.001 to 0.01 and ***P < 0.001.
