MCA PI: Middle cerebral artery pulsatility index; MCA S/D: Middle cerebral artery systolic/diastolic ratio; UA S/D: Umblical arterial systolic/diastolic ratio; UA PI: Umblical arterial pulsatility index; UtA PI: Uterine artery pulsatility index; UtA S/D: Uterine artery systolic/diastolic ratio. Composite adverse neonatal outcomes: Neonatal sepsis, need for mechanical ventilator, need for CPAP, 5th minute APGAR below 7, birth weight below 2000 g, neonatal low cord blood pH.
