Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
26 children (14 boys, 12 girls; median age: 7 years 7 months; range 5-11 years), with severe IgE-mediated egg allergy (EA) were recruited from the Pediatric and Allergology Unit of the Fatebenefratelli Hospital in Benevento, Italy, from January 2008 to December 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
6 children(4 males and 2 females)were excluded from the study: one child because the parents had a history of unreliable management of complications and treatments;2 children because of poorly controlled asthma;3 children because of a positive double-blind placebo-controlled food challenge (DBPCFC) at a dose of raw egg emulsion higher than 0.9 ml.

Reporting Groups
Specific Oral Tolerance Induction Specific oral tolerance induction consisted in the administration of increasing amounts of food antigen
Control controls were kept on an egg-free diet for 6 months
