TSH: thyroid-stimulating hormone; FT3: free triiodothyronine; FT4: free thyroxine. The multivariate model was adjusted for age, gender, body mass index, systolic blood pressure, diastolic blood pressure, waist circumference, triglyceride, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol, respectively.
