Multivariate logistic regression analyses of the factors associated with bronchial hyperresponsiveness in male and female adolescents

Variable	Males (n=78)			Females (n=35)
	aOR	95% CI	P value	aOR	95% CI	P value
Agea)	0.683	0.510–0.914	0.010	-	-	-
Atopic sensitization	7.207	0.599–86.721	0.120	-	-	-
Mold sensitization	5.569	1.702–18.221	0.005	-	-	-
Eosinophila)	1.002	1.000–1.003	0.026	-	-	-
FEV1/FVC <90%b)	-	-	-	7.500	1.715–32.796	0.007

aOR, adjusted odds ratio; CI, confidence interval; FEV₁, forced expiratory volume in 1 second; FVC, forced vital capacity.

Covariates included age, atopic dermatitis, atopic sensitization, tree/mold/pet sensitization, eosinophil count, FEV₁%, FEV₁/FVC.

^a)Quantitative variables were modeled continuously.

^b)Quantitative variables were modeled categorically.

Reference group was FEV₁/FVC ≥ 90%.

Boldface indicates a statistically significant difference with P<0.05.
