  • ORs are based on weighted data. N represents unweighted sample size.

    Early discharge defined as <2 nights for vaginal delivery and <4 nights for cesarean section.

  • * Odds of early versus later discharge in each group relative to the odds in the reference group.

  • Adjusted for all variables listed.
