Treatment:

Treatment ID:	TR002456
Treatment Summary:	Children were categorized as PA if they developed peanut allergy by mid-childhood and not peanut allergic (NPA) if they did not develop peanut allergy by mid-childhood. In study design table, subjects were sampled in infancy and then again mid childhood and placed into either PA or NPA for the purpose of this study. Peanut allergy was defined based on: (1) confirmed IgE-mediated reaction (e.g. positive doctor supervised oral food challenge to peanut and sensitization to peanut), or (2) convincing IgEmediated reaction (e.g. convincing reaction and sensitization to peanut) at any visit.16 This was “alternate definition 1” of the parent CoFAR2 study16 . We used this definition rather than the main definition to avoid inclusion of less convincing peanut allergy in case ascertainment, as the main definition16 also included those with peanut sensitization but no history of reaction.
