	Unadjusted OR^a (95% CI)	Adjusted OR^b (95% CI)	p-value^b
Gestational age in weeks	0.66 (0.58-0.73)	0.65 (0.57-0.75)	2.8×10⁻¹⁰
Intubation at birth	2.31 (1.56-3.48)	1.64 (1.06-2.54)	0.027
Any antenatal steroids	0.52 (0.34-0.80)	0.49 (0.30-0.79)	0.003

Mixed-effect logistic regression, adjusted by race, gestational age in weeks, intubation at birth, and any antenatal steroids, and accounted for dependence among siblings (as random effect).
