Comparison groups and outcomes
We compared women with IOL at 40 GW (40+0 to 40+6 GW), women with IOL at
41 GW (41+0 to 41+6 GW), and women with SOL in between 40+0 to 41+6 GW.
Artificial separation of membranes alone was not considered induction.
The incidence of births with one or more negative outcome(s) was our
primary outcome. In line with previous
literature,2,3,8 we defined negative outcomes as any
birth that included an
intervention (i.e. CS, OVD) and/or
a maternal or neonatal complication (i.e., was not completely
physiological) (see list in Table S2 ).
