Statistical analysis
The χ2 or Fisher exact test was used to compare categorical variables, while the Mann–Whitney U test was used to compare continuous variables between the 2 groups. Multivariate logistic regression analysis was performed to evaluate factors related to increasing egg consumption (dependent variable). Independent variables were selected based on their clinical relevance. To dichotomize the FAQLQ-PF total score and specific IgE level, a cutoff value for the 1–year outcome was determined using a receiver operating characteristics (ROC) curve. All reported P values are 2-tailed, with a P value of <.05 considered to be statistically significant. Statistical analyses were performed with GraphPad Prism 8 (GraphPad Software; La Jolla, California) and SPSS (version 26; SPSS; Chicago, Illinois).
