Adjusted associations of cystic fibrosis with neonatal adverse outcomes for a cohort of children with cystic fibrosis (CF present) compared to birth-year matched children without CF (CF absent) in Washington State from 1996- 2013 and 2006-2013

	1996-2013			2006-2013

	RR¹	(95% CI)	p-value	RR¹	(95% CI)	p-value

Low Birth Weight (<2500 grams)	3.5	(2.5-4.9)	<0.001	4.0	(2.5-6.3)	<0.001
Small for Gestational Age (<10^th percentile)	1.6	(1.1-2.4)	0.025	1.0	(0.4-2.4)	0.985
Pre-term Birth (<37 weeks)	3.0	(2.2-4.0)	<0.001	2.8	(1.9-4.3)	<0.001
Infant Death (Death <1 year)	6.8	(1.7-26.5)	0.006	12.1	(2.5-57.3)	0.002

Poisson regression analyses adjusted for maternal race (white/non-white)
