Information on gender was missing for 4 participants (3 adults and 1 adolescent not included in the table) who had provided urine samples. BMI categories for adolescents: international BMI definitions for normal weight, overweight or obese. IgE positivity defined by IgE ≥ 0.35 kU/L to at least 1 of 5 allergens tested (cat, timothy grass, Cladosporium, birch, and house dust mite).
