Odds ratio for wheezing based on positive test results for rhinovirus and titers of IgE antibodies (in international units per milliliter) to dust mite (D pteronyssinus)

Titer of IgE antibodies to mite:		<0.35 IU/mL		0.35-17.4 IU/mL		≥17.5 IU/mL
	No.	PCR negative	PCR positive (A/C)∗	PCR negative	PCR positive (A/C)∗	PCR negative	PCR positive (A/C)∗
Wheezing children	95	5	4† (2/2)	8	16 (3/10)	20	42 (8/30)
Nonwheezing children‡	186	73	15 (6/5)	43	7 (2/3)	45	3 (1/2)

Control	123	60	13 (6/4)	31	2 (1/1)	14	2 (1/1)
Odds ratio§		3.89 (0.9-16), P = .07		12.3 (3.8-39), P < .001		31.5 (8.3-108), P < .001

^∗The number in parentheses indicates the number of subjects with positive test results for group A and group C strains of rhinovirus.

^†Two of these 4 children had IgE antibody to B tropicalis: 24.3 and 1.66 IU/mL.

^‡Children with stable asthma combined with nonasthmatic control subjects.

^§Odds ratio for wheezing among rhinovirus-positive (real-time PCR) compared with rhinovirus-negative subjects.
