Data was compiled from the clinical records. The value refers to the association of the clinical variable with PTC recurrence according to the logistic regression analysis ( = 39); significance ( value < 0.05) is indicated in bold font. The USG classification of nodules was according to the Thyroid Imaging Reporting and Data System [9]. FV-PTC is the follicular variant of PTC. None of the samples displayed distant metastasis.
