No significant difference in concentrations of IgE specific against the mixture of food allergens was observed among the three basic groups (Supplementary Figure S4A), among the six subgroups of children divided according to their allergy at the age of 10 years (Supplementary Figure S4B), or when the children were divided only according to their own allergy status regardless of allergy status of their mother or possible EcO83 supplementation (Supplementary Figure S4C). The gene discussed is IGHE; the disease is allergic disease.
