3.1. Subject characteristics
As shown in Table 1, subjects in the CAE, PAE, OGE, and NEA groups did not differ in age. However, the CAE group had a higher male to female ratio compared to the other groups. Patients with egg allergy, including those in the CAE, PAE, and OGE groups, tended to be more comorbid with other allergic diseases than the NEA group. The CAE and PAE groups had an increased family history of allergic diseases compared to the OGE and NEA groups. Total IgE, EW-specific IgE, and OVA-specific IgE levels were higher in the CAE group, followed by the PAE, OGE, and NEA groups (Table 1 and Fig 1).
