a, c Representative images of CD8+T cells and FoxP3+ T cells in sections taken from subjects with either PD-L1+ or PD-L1− vessels in lung, kidney, and colon cancer. Original magnification, ×200. The number of intratumoral CD8+ T cells and FoxP3+ T cells from patients’ sections (kidney or colon cancer) associated with the percentage of PD-L1+ vessels. The determination as high and low were grouped by the median values. Lung adenocarcinoma (n = 41) b, colon cancer (n = 50) e and kidney cancer (n = 32) d; scale bars: 100 µm. Data are mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, Student’s t test.
