Search strategy
Although CRD methods were originally described in the 1990s [24], their clinical implementation in food allergy diagnosis did not occur until the early 2000s [25]. Therefore, we initiated our literature search in the early 2000s. We conducted a comprehensive search of the following databases from January 1, 2000, to March 8, 2023: EMBASE, PubMed, Cochrane Central Register of Controlled Trials, and Web of Science. We used the following keywords: ’Milk Hypersensitivity’, ’Milk Allergy’, ’Molecular Pathology’, ’Molecular Allergen Test’, and ’Specific Immunoglobulin E’. Our complete search strategy is provided in the online supplement (Table S2). No language restrictions were applied.
