Kaplan–Meier survival analysis stratified by NLR value 4.8 (low NLR group, < 4.8; high NLR group, ≥ 4.8). The differences between the two groups was assessed with log-rank test. The freedom from early adverse events in the low NLR group was significantly higher than high NLR group (P = 0.004). NLR, neutrophil-to-lymphocyte ratio
