简要总结
This is a multicentre, open-label, randomized controlled trial. A total of 340 singleton pregnancies with an EFW ≤10th percentile between 26+0 and 31+6 weeks will be recruited and randomly allocated to either the control or the intervention group. In the control group, standard Doppler-based management will be used. In the intervention group, different soluble fms-like tyrosine kinase to placental growth factor ratio (sFlt-1/PlGF) cutoffs will be incorporated to the current protocol to adjust the frequency of ultrasounds and to plan elective delivery.
