Receiver operating characteristic (ROC) curve for the retention index (RI) in the adenocarcinoma for lymph node metastasis. The area under the ROC curve (AUC) of the RI was 0.67 (95% CI 0.56–0.78), the threshold of RI for the nodal metastasis was 0.167, and the sensitivity and specificity were 0.500 and 0.793, respectively
