Table III. The Cox multivariate analysis of OS found a 13.7% increased risk of death for each unit increase in NLR (p-value<0.00000001), with each 10% increase in PD-L1 reducing the death risk by 7% (p-value=0.005).

OS: Overall survival; NSCLS NOS: non-small cell lung cancer not otherwise specified; PD-L1 TPS: programmed death ligand 1 tumor proportion score; bNLR: basal neutrophil-to-lymphocytes ratio; bPLR: basal platelets-to-lymphocytes ratio. Bold values denote statistical significance.
