The median number of positive IgE results to furry animal allergen molecules among children without asthma was 3, among all children with asthma 5.5 and among the children with troublesome asthma 9 (asthma vs. no asthma; p = 0.039; troublesome asthma vs. no asthma; p = 0.009) (Figure 1A). This evidence concerns the gene IGHE and asthma.
