Group differences were calculated with logistic regression, adjusted for age and sex (age and sex were only adjusted for the other, respectively)
Treatment status controlled: TSH 0.56–4.27 mU/L; overtreated: TSH < 0.56 mU/L; undertreated: TSH > 4.27 mU/L
*1 Adjusted for age and sex (overtreated compared with controlled)
*2 Adjusted for age and sex (undertreated compared with controlled)
