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).
