From: A nomogram to predict risk of lymph node metastasis in early gastric cancer
Validation of nomogram for predicting lymph node metastasis in early gastric cancer patients. (A) A receiver operating characteristics (ROC) curve of the multivariate logistic regression model. The AUC value was 0.842 (95%CI: 0.795 to 0.882), indicating a good discriminative ability (B). Calibration plot. The reference line represents perfect equality of the predicted probability and the actual incidence of lymph node metastasis.
