All values are expressed as geometric mean (95% confidence interval). Statistically significant values are shown in bold. Non-adjusted variables were used in Model 1. Variables in Model 1 plus age and sex were used in Model 2. Variables in Model 2 plus BMI, drink, exercise, income, and medical history of asthma, allergic rhinitis, and atopic dermatitis were used in Model 3.

Df: Dermatophagoidesfarina, IgE: immunoglobulin E
