In the obstetric side of the outcome spectrum the results for the PIH group and the control group were as follows:
induction, 49.6% and 5.4%, (p<0.001);
induction with artificial rupture of membranes, 8.0% and 20.3%, (p<0.02);
preterm delivery, 21.4% and 5.4%, (p<0.0002);
caesarean section rates, 27.7% and 3.1%, (p<0.001).
For the neonatal outcomes the results for the PIH and control groups were:
range of birth weight, 1-2.5 kg, 21% and 3.1%, (p<0.001);
range of birth weight 4.5-5.0 kg, 1.8% and 3.9%(p<0.05);
Apgar scores at 1 and 5 minutes were lower for neonates of PIH mothers than for those of control mothers (p<0.0003 and p<0.001, respectively);
perinatal outcome was much poorer in the PIH group, with p<0.001.
The perinatal mortality was 4% in the intervention and 0.8 % in the control; the p value was less than 0.001.
