Multivariate logistic regression-adjusted risk factors for severe disability¹

Characteristics	OR	95% CI
Cystic PVL	5.56	3.76	8.22
Congenital malformation	3.15	1.55	6.40
Severe IVH	3.05	2.45	3.79
Severe ROP or surgery for ROP	1.59	1.23	2.04
Oxygen at 36 weeks	1.53	1.28	1.84
Care giver education high school or less	1.49	1.27	1.75
Male gender	1.82	1.50	2.22
Delivery room cardiac compressions	1.83	1.49	2.25
Birth weight per decrease of 100-gram interval	1.26	1.17	1.36

p < 0.001 for all variables. Max. rescaled r² = 0.21. PVL = Periventricular leukomala-cia; IVH = intraventricular hemorrhage.

¹Adjusted for clustering of infants within centers and other factors in the model.
