Low nNO Prevalence Between Control, Biventricular CHD, and SV CHD Groups

Group	Total	Low nNO	% Low nNO	P Value	OR	95% CI
Controla	135	22	16	…	…	…
CHD (biventricular+SV)	471	145	31	0.001	2.28	1.37–3.94
SV CHD	106	45	42	<0.001	3.79	2.01–7.24
Biventricular CHD	365	100	27	0.010	1.94	1.14–3.40

N=606. CHD indicates congenital heart disease; CI, confidence interval; nNO, nasal NO; OR, odds ratio; and SV, single ventricle.

^a P values and ORs reflect comparison to control.
