  1. * Data on these atopy variables was recorded at enrollment into the CAMP trial (~10-12 years prior to both the gene expression and total serum IgE measurement).
  2. † Atopy defined as subjects with at least one positive allergen skin test.
  3. ‡ Data missing for skin test positive responses to Blattella Germanica in 1 subject, atopic dermatitis FEV1 and FEV1/FVC ratio in 9 subjects, for inhaled corticosteroids or oral prednisone in 23 subjects, and PC20 in 34 subjects.
  4. § Atopic dermatitis and allergic rhinitis were defined by physician diagnosis.
  5. â•‘ Refers to subjects who used these medications within 7 days of both the gene expression and total serum IgE measurement.
