Fig. 2From: PREPARE: protocol for a stepped wedge trial to evaluate whether a risk stratification model can reduce preterm deliveries among women with suspected or confirmed preterm pre-eclampsiaThe PREPARE protocol for the intervention proposed. The care providers of women, who are low risk by both sFlt-1/PlGF and fullPIERS, will be informed of the woman’s risk status in 3–4 h, with a recommendation that delivery be delayed unless the clinical condition deteriorates. Women will be reassessed at least twice weekly with fullPIERS and at least weekly with sFlt-1/PlGFBack to article page
