Figure 3From: Does recurrent laryngeal nerve lymph node metastasis really affect the prognosis in node-positive patients with squamous cell carcinoma of the middle thoracic esophagus? Survival curves of patients with different RLN node status (without lymph node metastasis vs. with RLN nodal involvement, P < 0.001; without lymph node metastasis vs. node-positive without RLN nodal involvement, P < 0.001; with RLN nodal involvement vs. node-positive without RLN nodal involvement, P = 0.979).
