Allergen-specific IgE levels were available for 592 (287 control subjects and 305 cases) of the 678 participating children.
Asthma was defined as physician-diagnosed asthma and wheeze in the previous year.
Multivariate logistic regression models were adjusted for age, sex, and household income in addition to the covariates listed in the first column.
Goodness of fit for each of the multivariate models was assessed by using the Hosmer-Lemeshow test (P =.9 for the model in nonatopic children and P =.8 for the model in atopic children).
