Correlation between Parturients’ Uterine Artery Blood Flow Spectra in the First and Second Trimesters of Pregnancy and Fetal Growth Restriction

Figure 3

Comparison of incidence rates of early diastolic notch of parturients’ uterine artery [n(%)]. The horizontal axes from left to right indicated bilateral, unilateral, and total incidences, and the vertical axis indicated the cases with early diastolic notch; the black areas indicated the FGR group, and the gray areas indicated the control group. # meant  < 0.05. (a) The early diastolic notch of the uterine artery in early pregnancy, no significant difference in bilateral incidence between the FGR group and control group was observed (20 vs. 21,  > 0.05), and the unilateral and total incidences were significantly higher in the FGR group than in the control group (21 vs. 10 and 41 vs. 31,  < 0.05). (b) The early diastolic notch of the uterine artery in the pregnant metaphase, and the bilateral, unilateral, and total incidences were significantly higher in the FGR group than in the control group (25 vs. 3, 12 vs. 2, and 37 vs. 5,  < 0.05).
