Fig. 1

a, b Typical images of CD34/PD-L1 (endothelial cells highly expressing PD-L1) immunostaining in lung adenocarcinoma (n = 35), kidney (n = 30), and colon cancer (n = 30), scale bars: 50 μm. Kaplan–Meier survival curves of OS c and PFS c of patients with lung adenocarcinoma exhibiting high (red) or low (green) VEC-PD-L1. d The correlation of PD-L1+ vessels and PD-L1+ tumor tissues (n = 106). Data are mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, Student’s t test.
