EDA vaginal delivery with epidural analgesia, CS caesarean section in general anaesthesia, bpm^− 1: a change of the dependent parameter per a difference of heart rate one beat per minute. EDA and CS are dummy-coded and indicate the difference between EDA/CS mode of delivery and vaginal delivery without analgesia
