bold = statistically significantly different from zero. rph = phenotypic correlation, i.e. the correlation between variables within individuals, within-twin/cross-trait. ICC = intra-class correlation, i.e. the correlation between the same variable measured in one twin and in her co-twin, cross-twin/within-trait. CTCT = cross-twin/cross-trait correlation, i.e. the correlation between one variable in one twin and another in the co-twin, IgE level=continuous value of allergen-specific IgE level. Note: Correlations adjusted for covariates sex, age at examination, and ICS-medication (asthma not adjusted for ICS).
Table 3. Results from multivariate modeling. Phenotypic correlation from best-fitting model; due to Asthma and FENO and/or from Eosinophils and IgE level.
