Figure 1:

Overlap between pregnancy complications experienced (a) by the same donor across potentially multiple pregnancies, and (b) within the same pregnancy. If a donor was noted as experiencing both gestational hypertension and pre-eclampsia or eclampsia in a pregnancy they were classified as having pre-eclampsia or eclampsia in Figure 1a. Six individuals who were noted as having complications before donation, but with uncertain information about which pregnancies had the complication were excluded from Figure 1b.
