Multivariate logistic regression analyses of the baseline factors at age 6 years associated with persistent bronchial hyperresponsiveness in male and female adolescents

Variable	Males (n=25)			Females (n=15)
	aOR	95% CI	P value	aOR	95% CI	P value
Mold sensitization	7.718	1.243–41.440	0.028
Methacholine PC20a)	0.805	0.715–0.905	0.000	0.710	0.541–0.932	0.014

aOR, adjusted odds ratio; CI, confidence interval; FEV₁, forced expiratory volume in 1 second; PC₂₀, provocation concentration causing a 20% fall in FEV₁.

Covariates included mold sensitization, FEV₁%^a), and methacholine PC₂₀^a).

^a)Quantitative variables were modeled continuously.

Boldface indicates a statistically significant difference with P<0.05.
