We investigated the relationship between neutrophil–lymphocyte ratio (NLR) and restenosis in patients with femoropopliteal arterial disease following drug-coated balloon (DCB) angioplasty. Patients (n = 120) were divided into 3 groups according to the development of restenosis and the time of restenosis occurrence. The postoperative NLR was higher in the late-restenosis group than that in the no-restenosis group (3.53 vs 2.70; p = .011). In multivariate logistic analysis, postoperative NLR was an independent predictor of late restenosis (odds ratio: 1.404, 95% confidence interval: 1.073–1.839; p = .014). The postoperative NLR cutoff value for predicting late restenosis was 2.78 with a sensitivity of 80.8% and a specificity of 53.2% (area under the ROC curve was .666 (95% CI: .541–.791, p = .010). The incidence of late restenosis in the NLR ≥2.78 group was higher than that in the NLR
