Food allergy presence
Presence of FA was assessed at follow-up and participants were assigned
to one of three groups, previously reported by
Westerlaken-van Ginkel et
al. in adults.12 The groups represented those who did
not report FA (noFA ), those likely to have a food allergy
(likelyFA ) and those who could not be assigned to either of those
groups, termed indeterminate (indeterminateFA ). In short,
participants were classified as likelyFA if they stated:
at least one food AND at least one symptom consistent with immediate
allergic reactions to food AND
other characteristics of FA consistent with immediate allergic
reactions to food
Further details on the definitions are provided in the supplement.
