  1. FHS food hypersensitivity, IQR interquartile range, SD standard deviation.
  2. aSevere: breathlessness, fainting or dizziness, emergency injection required and have both skin-mucosal and gastrointestinal symptoms. Mild: rash or itchy skin, diarrhea or vomiting, runny or stuffy nose, severe headaches, itching, tingling or swelling in mouth, difficulty swallowing.
  3. bUnivariate tests: t-test for age; chi-square test for prevalence; Wilcoxon rank sum test for total IgE level and age of first FHS.
  4. cMultiple logistic regression: factors with p < 0.05 in univariate tests were included. Sex and country were adjusted.
  5. dAmong the 655 had self-reported FHS, 44 did not provide details of symptoms.
