TG and thyroid gland disorder: Similar statistic analysis also found a significant association between RC and Tg-abs (p < 0.001, OR = 5.466, 95%CI = 2.177–13.723), and after adjusting for gender, age, marriage status, education, antidepressants treatment, comorbidity of thyroid diseases, and thyroid function (serum levels of FT3, FT4 and TSH), the association remained significant (p = 0.002).
