A and B, Kaplan–Meier curves of overall survival stratified by PD-L1 strong (tumor cell proportion score ≥50%), moderate (1–49%) and negative (<1%) expression in non-small cell carcinoma (a, N = 713) and adenocarcinoma (b, N = 399). c, d Kaplan–Meier curves of overall survival stratified by PD-L1 positive (tumor cell proportion score ≥1%) and negative (<1%) expression in non-small cell carcinoma (C, N = 713) and adenocarcinoma (D, N = 399)
