- Note: Perchlorate and iodine were corrected by urinary specific gravity (USG); Perchlorate, iodine, gender, age, BMI, smoking, and drinking were included in the model. Perchlorate, iodine, TSH, TPOAb and TgAb were natural logarithm conversion. CI confidence interval, TSH thyroid stimulating hormone, TT3 triiodothyronine; TT4 thyroxine, FT3 free triiodothyronine, FT4 free thyroxine, TPOAb thyroid peroxidase antibody, TgAb thyroglobulin antibody
