Recurrence-free survival (PFS) and overall survival (OS) curves according to tumor proportion score (TPS) for tumoral PD-L1 expression status among patients with low neutrophil-to-lymphocyte ratio (NLR, less than 2.2) or among high NLR (2.2 or higher) patients. The cut-off value for NLR and TPS were 2.2 and 1, respectively.
