Predictive accuracy of the nomogram to predict con-CLNM in uni-PTC patients. (a) ROC curve for the model (blue line), male sex (gray line), Hashimoto's thyroiditis (green line), capsular invasion (orange line), the ratio of ipsi-CLNM ≥0.16 (red line), and ipsi-LLNM (purple line). (b) Calibration plots of the nomogram for predicting con-CLNM in uni-PTC patients. (c) Decision curve for nomogram to predict con-CLNM in uni-PTC patients. Con-CLNM, contralateral central lymph node metastasis; ipsi-CLNM, ipsilateral central lymph node metastasis; ipsi-LLNM, ipsilateral lateral lymph node metastasis; ROC curve, receiver operating characteristic curve; uni-PTC, unilateral papillary thyroid carcinoma.
