Associations between IL-22 expression and allergen-specific IgE reactions [19]. The numbers of subjects in each category were as follows: egg There were 8 non-asthmatic (control) egg-specific IgE-negative children, 7 control egg-specific IgE-positive children, 4 asthmatic egg-specific IgE-negative children, and 11 asthmatic egg-specific IgE-positive children. Milk There were 13 control milk-specific IgE-negative children, 2 control milk-specific IgE-positive children, 9 asthmatic milk-specific IgE-negative children, and 6 asthmatic milk-specific IgE-positive children. Wheat There were 13 control wheat-specific IgE-negative children, 2 control wheat-specific IgE-positive children, 9 asthmatic wheat-specific IgE-negative children, and 6 asthmatic wheat-specific IgE-positive children. P values were obtained by Mann–Whitney U test
