Planned caesarean section decreases the risk of adverse perinatal outcome due to both labour and delivery complications in the Term Breech Trial

OBJECTIVE: To determine if the decreased risk of adverse perinatal outcome, with a policy of planned caesarean, in the Term Breech Trial, was due to a reduction of problems of labour, problems of delivery or unrelated problems. DESIGN: Secondary analysis of data from the Term Breech Trial, a randomised controlled trial of planned caesarean versus planned vaginal birth for the singleton fetus in frank or complete breech presentation at term.
