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.
