Categorical variables: n/N yes/total number (%). Continuous variables: median (interquartile range).
p for comparisons of combined anthroposophic and partly anthroposophic versus nonanthroposophic lifestyle group and for girls vs boys regarding sensitization to allergens. Categorical variables: Fisher’s exact test; continuous variables: Mann-Whitney-Wilcoxon rank-sum test.
Classified as sensitized if IgE level was ≥0.35 /L measured using Phadiatop™ (Thermo Fisher Scientific) a mix of 11 aeroallergens.
Classified as sensitized if IgE level was ≥0.35 /L for at least one of the three food allergens analyzed using ImmunoCAP™ (Thermo Fisher Scientific).
Classified as sensitized if IgE level was ≥0.35 /L for at least one of the six food allergens analyzed using a food mix, fx5, followed by separate ImmunoCAP™ tests (Thermo Fisher Scientific).
Classified as sensitized if IgE level was ≥0.35 /L for at least one of the four aeroallergens analyzed using ImmunoCap™ (Thermo Fisher Scientific).
Classified as sensitized if IgE level was ≥0.35 /L for at least one of the 9 aeroallergens analyzed using Phadiatop™ followed by separate ImmunoCAP™ tests (Thermo Fisher Scientific).
