Data are presented as median (interquartile range).
GDM, gestational diabetes mellitus; CRL, crown-lump length; NT, nuchal translucency; PI, pulsatility index; MAP, mean arterial pressure; PAPP-A, pregnancy-associated plasma protein A; β-hCG, beta-human chorionic gonadotropin; PLGF, placental growth factor.
*P < 0.05 was considered statistically significant.
