  1. Italic denotes statistically significant results
  2. HRQL is on a scale from 1 to 7, where 1 = best possible HRQL, and 7 = worst possible HRQL
  3. HRQL health-related quality of life, AADR allergen avoidance and dietary restrictions, EI emotional impact, RAE risk of accidental exposure
  4. p < 0.05
  5. p < 0.01
  6. aRepresent mean difference in outcome compared to the reference group. Calculated by linear regression, adjusted for number of food allergies and prescription of an epinephrine autoinjector
