Data are expressed as a number with percentage for qualitative variables or mean ± standard deviation for quantitative variables. BMI, body mass index; TT3, total triiodothyronine; TT4, total thyroxine; FT3, free triiodothyronine; FT4, free thyroxine; TSH, thyroid stimulating hormone; Δ, the difference of thyroid-related hormone after treatment minus that before treatment.

^*The correlation was significant at the 0.05 level (P < 0.05).
