Fig. 1From: Correlation analysis of risk factors for cervical lymphatic metastasis in papillary thyroid carcinomaROC curve analysis predicts CLNM based on tumor lesion size. The ROC results show that 0.855 is the critical tumor lesion size value and the best point for predicting CLNM. The sensitivity, specificity, AUC, and 95%CI at this value are 57.9%, 69%, 0.269, and 0.639–0.707, respectivelyBack to article page
