Data for IUGR and pre-eclampsia are presented together. Of the 52 cases in the study, 44 were IUGR and eight were pre-eclampsia, but it is not possible to extract data for the two conditions separately. As the majority of the cases were not pre-eclampsia, the findings are probably not relevant to the question
