Study design and participants
We conducted a national cross-sectional study based on an online survey.
French obstetricians were invited to participate during congresses and
through national networks. Participants could be licenced obstetricians
or specialized residents in their fourth year or higher and were
required to have had regular practice in obstetrics in the previous
year. This study was approved by the local ethics committee
(Aix-Marseille University 2021-04-08-06).
