No heterogeneity (of effect of throughput level) was found across gestational age for any outcome.
*Test for significance of effect of throughput, adjusted for gestational age and birthweight for gestation; further adjustment for antenatal transfer did not materially change the ORs or CIs for any of the outcomes.
aOR, OR adjusted for gestational age and birthweight for gestation based on population alive at start of time period.
