Linear correlation between PD-L1-expressing CD14⁺ monocytes and T cell subsets. Association between the percentage of peripheral PD-L1-expressing CD14⁺ monocytes and PD-L1-expressing a CD8⁺ T cells or b CD4⁺ T cells, and peripheral PD-L1-expressing CD14⁺ monocytes and whole c CD8⁺ T cells or d CD4⁺ T cells. Each dot represents one specimen from a total of 21 or 18 patients
