  1. Note: For categorical variables, the multivariable OR is the odds of intrapartum transfer for the given category, relative to the first category, adjusted for the effects of the other listed variables. Three singleton pregnancies were not included for missing intrapartum transfer status
  2. a A quadratic function was fitted for maternal age, providing linear and quadratic regression coefficients; this means that a single odds ratio for maternal age does not exist
  3. bOnly 4 of 193 ‘Muslim or other’ were not Muslim
