Interventionist care vs expectant care

Intraventricular haemorrhage or hypoxic ischaemic encephalopathy · women with severe pre‐eclampsia between 24 and 34 weeks' gestation

Interventionist care probably leads to higher intraventricular haemorrhage or hypoxic ischaemic encephalopathy compared with expectant (delayed delivery) care (moderate certainty).
