Randomization and Grouping
FOOD ALLERGIES
Allocation was performed anonymously using the envelope method, and each facility randomized allocation adjustment factors using the substitution block method. Physicians who followed up the children and evaluated their food allergies were blinded to the randomization results.Mothers and their neonates were randomized (1:1 ratio) into an MEC group, wherein the mother consumed 1 whole egg per day between 0 and 5 days after delivery, and a maternal egg elimination (MEE) group, wherein the mother eliminated eggs from her diet between 0 and 5 days after delivery.
