  1. aData are shown as mean ± SD and median, IQR. ‡IQR interquartile range, Y year, TTP Time to pregnancy was defined just for participants with Hx of pregnancy (the time between the decision to pregnancy and become pregnant), mth month, BMI body mass index, SBP systolic blood pressure, DBP diastolic blood pressure, FBS fasting blood sugar, TSH thyrotropin, FT4 free thyroxine, TPO thyroid peroxidase antibody
  2. *P-value obtained from t-student or Mann-Whitney U tests for normal or non-normal continuous variables,significant level was considered as p-value < 0.05
