Previous studies have shown that “the gut microbiota differs in composition and diversity during the first months of life in children who later do or do not have allergic disease," but researchers who focused on immunoglobulin A prevalence made a different finding.
The pros identified included the possibility of EMDs improving adherence, that the devices might help motivate patients through creating a sense of independence and accountability, and that the data generated could help in building a trusting relationship between clinician and patient.
