Main findings
There are three main findings of this large prospective screening study for adverse pregnancy outcome. First, about 60% of antepartum stillbirths are related to placental dysfunction and in more 90% of such cases the fetuses are SGA. Second, in screening for placental dysfunction related stillbirth by a combination of maternal risk factors, EFW and UtA-PI utilising the competing risks model for SGA7, the predictive performance is similar to that achieved in screening by a specific logistic regression model for placental dysfunction related stillbirth1. Third, the performance of screening by the competing risks model for SGA is by far superior to the RCOG guideline for the investigation and management of the SGA fetus 3.
