Prediction of lymph node metastasis in early esophageal cancer

Figure 1 Nomogram predicting the risk of lymph node metastasis in patients with early esophageal cancer. Harrell’s concordance index was 0.790 [95% confidence interval (CI): 0.717-0.864] and 0.789 (95%CI: 0.709-0.869) in the training and validation sets, respectively. The corresponding cutoff values were 0.142 and 0.224. The P value in the Hosmer-Lemeshow test of the derivation and validation cohorts were both > 0.05. LNM: Lymph node metastasis.
