  • ↵* Participant had a history suggestive of CMA beginning at 6 months of age and ongoing symptoms of atopic dermatitis at enrolment.

  • ↵† Participant had sufficient evidence of CMA (exhibited multiple symptoms upon inadvertent CM intake within 3 months of enrolment) although CAP RAST to CM was slightly <5 kUA/l.

  • CM, cow's milk; CMA, cow's milk allergy; CMP, cow's milk protein; DBPCFC, double-blind placebo-controlled food challenge.
