Definition of abbreviations: CI = confidence interval; OR = odds ratio; RV = rhinovirus.

Aeroallergen sensitization was determined by RAST in the first and third year of life. ORs for Year 6 asthma were determined by logistic regression analyses. Aeroallergen sensitization did not modify the effects of RV wheezing on subsequent asthma risk (interaction P value, 0.61 and 0.99, in the 1st and 3rd yr of life, respectively).
