"Data used in the current analysis come from tertiary referral centres specializing in paediatric allergology, dermatology, or both, in Germany, France, Austria, Switzerland, Spain, Greece, Italy, Ireland, Bulgaria, Poland, and Brazil (Figure S1). Professionals at the referral centres were required to enter the patients' details into the registry within 1 year of their anaphylaxis episode. The study was registered at ClinicalTrials.gov (Identifier: NCT05210543), and it was approved by both the ethics committee at the Charité ‐ Universitätsmedizin Berlin, in Germany (EA1/079/06), as well as the ethics committees local to the participating referral centres."
