Prediction of lymph node metastasis in early esophageal cancer

Figure 2 Nomogram predicting the risk of lymph node metastasis in patients with early esophageal cancer. The area under the curve was 0.80 [95% confidence interval (CI): 0.739-0.856] in the training cohort and 0.814 (95%CI, 0.725-0.900) in the validation cohort. The optimal cutoff value was 20%. Tumor grade I: High differentiation; Tumor grade II + III: moderate differentiation and poor differentiation. LNM: Lymph node metastasis.
