This difference remained significant after controlling for antenatal, intra\u2010operative and immediate postoperative variables. Modifiable variables were identified that may mitigate the effects of severe obesity.

three\u00a0minutes respectively (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001), while epidural top\u2010up significantly lessened mean anaesthetic in\u2010theatre preparation duration by
