Neutrophil-to-lymphocyte ratio (NLR) ≥ 3 is significantly associated with worse overall survival (A) and inferior disease-free survival (B) in patients with locally advanced esophageal squamous cell carcinoma receiving preoperative chemoradiotherapy followed by esophagectomy (solid line indicates NLR < 3, dotted line indicates NLR ≥ 3)
