  1. HR: Hazard ratio.
  2. *Only significant predictors are indicated.
  3. **Potential predictors for the Cox regression included sex, ethnicity, age at study entry (i.e., at the time the patient starts to be observed, which could be up to one year prior to the initial questionnaire), disease duration, source of recruitment (i.e., food allergy advocacy associations versus allergy clinics), other atopic conditions, severity of initial reaction to peanut, whether the child attended a school prohibiting peanut, and parental factors (i.e., living arrangement, age, level of education and employment).
