  • * Among vaginal deliveries, P < .01 for Fisher exact tests between LOS categories for each characteristic listed. Among cesarean section deliveries, P < .01 for Fisher exact tests between LOS categories for maternal characteristics and newborn race variables; P < .05 for Fisher exact tests between LOS categories for mild/moderate trauma, infection, and deaths within 28 days.

  • Five-minute Apgar score of <7.
