Fig. 2From: Mediastinoscopy-assisted esophagectomy for T2 middle and lower thoracic esophageal squamous cell carcinoma patientsOverall survival curves after MAE and Ivor Lewis procedure. The mean survival time was 59.1 months [95% confidence interval (CI) 45.2–72.9] for the MAE group and 53.3 months (95% CI 38.2–68.4) for the Ivor Lewis group. No significant difference was found in the long-term survival rate between the two groups (P = 0.635)Back to article page
