|Risk of adverse neonatal outcomes after birth for 1,016a publicly insured women compared with 1,016a privately insured women that were individually matched on the propensity score of maternal demographics|
|n||Unadjusted||Adjusted for antenatal factors|
|public/private||RR (95% CI)||ARR (95% CI)b|
|Low Apgar score at 5 mins <7c||15/6||2.50 (0.97–6.44)||2.63 (1.06–6.52)|
|>1 min to unassisted breathinge||137/87||1.57 (1.22–2.02)||1.61 (1.25–2.07)|
|Admission to special care||96/251||0.83 (0.80–0.87)||0.84 (0.80–0.87)|
a Restricted to singleton, preterm births (32–36 weeks gestation), where the infant was live-born and without birth defects.
b Adjusted for threatened abortion, threatened pre-term labour, pre-eclampsia, placenta-praevia, and pre-labour rupture of membranes.
c Apgar score at 5 minutes = 0–6.
d Too small sample size for reliable estimation.
e >1 minutes until establishment of unassisted breathing.
f Endotracheal intubation or external cardiac massage.
