The study cohort included patients with multiple food allergies, including a combination of HE, CM, wheat, and peanut allergies. Total IgE and antigen-sIgE levels were converted to log 10
values, which were used in the analysis. †Antigen-sIgE levels indicate egg white- or milk-sIgE levels. Multiple logistic regression analysis was performed in A) all cohorts, (B) HE allergy, and (C) CM allergy, respectively. Patients with wheat or peanut allergies were ineligible for inclusion in the multiple logistic regression analysis because of the small sample size. Additionally, for HE or CM allergies, egg white- and ovomucoid-sIgE or milk- and casein-sIgE levels would have been collinear. Therefore, egg white and milk sIgE levels were used as variables in the multiple logistic regression analysis of outcomes as shown in Supplementary Table S5. HE, hen’s egg; CM, cow’s milk
