Data are presented as mean ± SD or median (interquartile range); compared with low-normal TSH group, *P < 0.05; age, after adjusting for gender; waist circumference, BMI, after adjusting for age, gender, and HOMA-IR; HOMA-IR, after adjusting for age, gender, and BMI; others, after adjusting for age, gender, HOMA-IR, and BMI.
