A
For the prospective analyses, ages are time 1 ages. Time 1 EIW was evaluated as a predictor of time 2 ED visits and hospitalizations (2 years later).
B
Seroatopy was defined as measurable IgE (≥0.35 IU/ml) to at least one of the allergens (dust mite, cockroach, mouse, cat, dog, grass pollen, tree pollen, ragweed pollen and mixed mold) tested at age 7 years.
