Data from the cross-sectional study.
Allergy (any of asthma, allergic rhinoconjunctivitis, or eczema) in relation to the number of household cats and dogs during the child’s first year of life. Allergy last year required current symptoms, i.e. symptoms in the last 12 months.

Allergy (any of asthma, allergic rhinoconjunctivitis, or eczema) in relation to the number of household cats and dogs when the child was 6 months old. Allergy last year required current symptoms, i.e. symptoms in the last 12 months.

Sensitisation in parents, measured with Phadiatop tests, in relation to the number of household cats and dogs the family had when their child was 6 months old.

Orthogonal projection to latent structures loading plot showing associations between the number of household cats and dogs when the child was 6 months old (Y variable), and a set of 15 X variables.
The outcome variables for lung function (forced expiratory volume in 1 s [FEV1]/forced vital capacity [FVC]), bronchial hyperresponsiveness (BHR), blood eosinophil count (B-Eos), percentage of blood eosinophils (Eosproc), total immunoglobulin (IgE), and skin-prick tests (SPTs) were from the age 8–9 years follow-up. SPTs are given as weal diameter. X variable bars pointing in the same direction as the Y variable are positively associated with the Y variable, and bars pointing in the opposite direction are negatively associated. The height of the bars shows the B-coefficients for scaled and centered data, with 95% confidence intervals.
