| The adjusted model 1 was adjusted for maternal age, maternal educational level, current employment status, parity, pre-pregnancy body mass index (BMI) and gestational age of thyroid function testing. The adjusted model 2 was additionally adjusted for thyroid stimulating hormone (TSH) and free thyroxine (FT4) levels. TPOAb, thyroid peroxidase antibody; EFW, estimate fetal weight; AC, abdominal circumference; BPD, biparietal diameter; FL, femur length; HC, head circumference; FGR, fetal growth restriction. | |||||
