No heterogeneity was detected for any outcome in the effect of neonatal transfer at different gestational ages.
*p Value for overall significance of transfer adjusted for gestational age and birthweight for gestation.
aOR, OR adjusted for gestational age and birthweight for gestation based on population alive at start of time period; NNT, neonatal transfer.
