Perinatal mortality in breech presentations as compared to vertex presentations in singleton pregnancies: an analysis based upon 57 819 computer-registered pregnancies in The Netherlands

In 1982, nationwide registration of obstetric data was instituted in The Netherlands with about 70% of all Dutch hospitals participating.
