Exo-PD-L1 and sPDL1 levels in serum of NSCLC patients. a, b Exo-PD-L1 levels were higher in NSCLC patients with advanced stage (a), larger tumor size (> 2.5 cm), positive lymph node status (N1–N3) and distant metastasis (M1) (b); *p < 0.05; ***p < 0.001; #p < 0.05; ##p < 0.01. c, d sPDL1 levels were not significantly different in NSCLC patients stratified by stage (c), lymph node status and metastasis except for tumor size (> 2.5 cm) (d); *p < 0.05
