CI = confidence interval; OR = odds ratio; SGA = small for gestational age (< 10th percentile); SD = standard deviation.
Only singleton pregnancies and live-born neonates without congenital abnormalities and estimated gestational age (EGA) > 28 weeks.
Only singleton pregnancies and live-born neonates without congenital abnormalities and EGA > 28 weeks and birthweight only reported if measured in the first 72 hours of life.
Three home deliveries and one birth at hospital and no known Apgar scores.
