Overall survival curve and disease-free survival curves stratified by RLN lymph node metastasis status in 199 patients with RLN lymph nodes retrieved in the whole cohort (a p < 0.001 and b p < 0.001, respectively), 164 patients with RLN lymph nodes retrieved in the MIILE group (c p < 0.001 and d p < 0.001, respectively), and 35 patients with RLN lymph nodes retrieved in the Sweet group (e p = 0.776 and f p = 0.816, respectively). MIILE = minimally invasive Ivor Lewis esophagectomy. RLN = recurrent laryngeal nerve. LN = lymph node
