0.05). Pearson’s correlation analysis showed in GDM group that there was a highly statistically significant negative correlation between birth weight and the following ultrasound indices: (UA_RI, UA_S/D, UA_PI, MCA_RI and MCA_PI) and that there was a statistically significant positive correlation between birth weight & RA_RI (P<0.01) (r = −0.273, −0.453, −0.537, −0.237, −0.265 and 0.169 respectively, P < 0.05), but As regard NC group there was a highly statistically significant negative correlation between birth weight and the following ultrasound indices: (UA_S/D, UA_RI, UA_PI and MCA_PI) (r = 0.148, -0.360, -0.252 and -0.184 respectively, P < 0.05) but no correlation was found with any of renal artery indices (P > 0.05). Conclusions: Fetal hemodynamic indices in late pregnancy might be helpful for estimating newborn birth weight in women with GDM.]]>
