  1. aOdds ratio of having a spontaneous vaginal delivery or operative vaginal birth with respect to maternal country of birth
  2. bOdds ratio of having an spontaneous vaginal delivery or operative vaginal birth after adjustment for all variables significant at the univariate level. These variables included maternal age group, BMI, parity, baby birthweight, private care, length of first stage, length of second stage, induction of labor, augmentation of labor and use of epidural
  3. cOdds ratio of having an emergency cesarean birth with respect to maternal country of birth
  4. dOdds ratio of having an emergency cesarean birth after adjustment for all variables significant at univariate level. These variables included maternal age group, maternal BMI, parity, past cesarean, pre-existing diabetes, gestational hypertension/PE/HELLP, gestational age, baby gender, baby birthweight, private patient, prolonged first stage, labor induced, labor augmented and use of epidural
  5. eOdds ratio of having a planned cesarean section with respect to maternal country of birth
  6. fOdds ratio of having an planned/elective cesarean birth after adjustment for all variables significant at univariate level. These variables included maternal age group, maternal BMI, parity, past cesarean, baby gender and private patient
