This is not surprising considering that the trials differ in the populations studied (variable rates of HDP, pre-eclampsia), gestational age at enrolment (13–32 weeks), sample size in each group (22–4161) and definition of the reported outcomes. These trials were the subject of two recent reviews that reached different conclusions about the benefits of calcium supplementation during pregnancy.1 2

The data source was the Cochrane Pregnancy and Childbirth Groups Trials Register, plus some study authors were contacted.
