Three subgroups were analyzed: women with a history of elective cesarean section, those with a history of cesarean section during the first stage of labor, and those with a history of cesarean section during the second stage of labor. The two stages were defined depending on the cervical dilation (first stage &lt;10\u2009cm, second stage: full dilatation). The duration of labor was defined as time between regular contractions or time of rupture of the membranes (whatever was first) to childbirth.
