A Prediction Model for Contralateral Central Neck Lymph Node Metastases in Unilateral Papillary Thyroid Cancer

Figure 1

Diagnostic value of risk factors for predicting con-CLNM in uni-PTC patients. (a) ROC curve for age (blue line), tumor size (orange line), number of ipsi-CLNM (green line), and the ratio of ipsi-CLNM (red line). (b), (c) The correlation analyses of the number of ipsi-CLNM and risk of con-CLNM or the ratio of ipsi-CLNM and risk of con-CLNM in uni-PTC patients are shown, Pearson’s r test, n = 250, . Con-CLNM, contralateral central lymph node metastasis; ipsi-CLNM, ipsilateral central lymph node metastasis; ROC curve, receiver operating characteristic curve; uni-PTC, unilateral papillary thyroid carcinoma.
