Pre-eclampsia remains a leading cause of maternal and perinatal mortality and morbidity worldwide.1 In the linked study (doi:10.1136/bmj.d1875), North and colleagues present a predictive model for pre-eclampsia that is based on routine clinical data.2

The study used data from 3529 “healthy” nulliparous women with a singleton pregnancy participating in the Screening for Pregnancy Endpoints (SCOPE) study.3 The SCOPE study is a large international undertaking that makes an important contribution towards assessing potential risk markers, individually and in combination. North and colleagues have identified nine clinical predictors of pre-eclampsia: one protective (miscarriage at ≤10 weeks’ gestation with the same partner) and eight associated with increased risk (younger maternal age, higher mean arterial blood pressure, higher body mass index, family history of pre-eclampsia, family history of coronary heart disease, the woman having a lower birth weight, vaginal bleeding for at least five days during early pregnancy, and duration of sexual relationship six months or less). All can be collected easily in routine clinical practice, and …
