Groups and endpoints
The participants were divided into two groups: the training group
(obstetricians who participated in a training course in physiology-based
interpretation of CTG) and the control group (no participation in such a
course declared).
The primary endpoint was the difference between groups in the median
number of second-line methods that the participants would have
performed.
The secondary endpoints were the median number of decisions to continue
labour without a second-line method when the real outcome was a
caesarean section and the median number of decisions to perform a
caesarean section when the real outcome was a vaginal delivery.
