The results reported were similar both in the different PD-L1 expression groups, PD-L1 < 1% (HR 0.65; 95% CI 0.33–1.23), 1–49% (HR 0.31; 95% CI 0.17–0.54), and ≥50% (HR 0.31; 95% CI 0.15–0.60), and tumor histology, non-squamous disease (HR 0.54; 95% CI 0.27–1.09), and squamous disease (HR 0.35; 95% CI 0.24–0.53). This evidence concerns the gene CD274 and neoplasm.
