Abstract

We acknowledge that gaps in the childhood food allergy literature including intermediate- to long-term outcomes are a key barrier to accurately model the costs and benefits of childhood food allergy technologies. The limited evidence base affects the ability to conduct economic evaluations that will score highly with traditional appraisal checklists and that a pragmatic application of economic evaluation in such circumstances can provide important contributions to inform policy. Nonetheless, although we do know the authors of some included studies, we chose not to reach out for additional information or clarification because this approach is not considered best practice in systematic reviews given that this may create inconsistencies in the treatment of included studies.
