Generation of the con-CLNM score by nomogram. (a) Nomogram for predicting con-CLNM in uni-PTC patients. (b) A uni-PTC patient with the ratio of ipsi-CLNM ≥0.16, male sex, present capsular invasion, without Hashimoto’s thyroiditis, and present ipsi-LLNM has a con-CLNM of 90%. Con-CLNM, contralateral central lymph node metastasis; ipsi-CLNM, ipsilateral central lymph node metastasis; ipsi-LLNM, ipsilateral lateral lymph node metastasis; uni-PTC, unilateral papillary thyroid carcinoma.
