HV min and STV msec in mean + 2 S.D.
a) No significant difference was found for FHR, Acc (accelerations) 10 min, and FM (fetal movements) between groups. b) LV (low variation) min and LV msec were absent in cCTG parameters of fetuses in the study group, c) cCTG traces in the study group were repeated weekly as for controls until delivery.
