Regression results: factors associated with composite severe childhood morbidity at age 2 years^a

Variable	OR	95% CI	P value
PPROM prior to 25 wks’ gestation	1.57	1.12–2.20	.009
Severe composite neonatal morbidity	2.13	1.56–2.90	< .001
White	0.82	0.63–1.06	.123
Male infant	1.56	1.22–2.00	< .001
Delivery gestational age (per 1-wk interval)	0.86	0.81–0.92	< .001
Cesarean delivery	1.31	1.02–1.68	.031
Maternal drug use during pregnancy	1.65	1.14–2.37	.008

CI, confidence interval; OR, odds ratio; PPROM, preterm premature rupture of membranes.

Other factors included in the initial model but not remaining in the final model (P > .20) included chorioamnionitis and treatment group (magnesium sulfate vs placebo).
