*Number of informative families.

STR = skin test reactivity.

+ and - signs preceding significant P values indicate the direction of the observed associations.

In Costa Rica, a positive IgE to B. germanica was defined as a value >= 0.35 IU/ml. Allergen-specific IgE was not measured in CAMP.

3' UTR = 3' untranslated region.

For ease of exposition, only p values < 0.1 are displayed. A dash "-" has been used to represent p values ≥ 0.1.
