Aim of the study was to analyse data on cervical dilation and fetal descent patterns in low-risk women, who did or did not receive intermittent low-dose epidural analgesia (EA), and who had either a vaginal or a caesarean delivery. Therefore, we conducted a retrospective analysis, retrieving data from October 1st 2008 to October 31st 2018. We selected 6030 women categorized as Robson Group 1, divided into four groups according to the mode of delivery (vaginal or caesarean) and the presence of EA: * Vaginal delivery with EA (VD-e) * Vaginal delivery without EA (VD-n) * Caesarean delivery with EA (CD-e) * Caesarean delivery without EA (CD-n)
