Comments regarding Table 2: a51.8% (43/83) were BE tolerant, egg allergic (8/48 BE tolerant children had raw egg OFC, 6/8 tolerated raw egg and were excluded from final analysis). b1/9 with suboptimal BE OFC tolerated a raw egg OFC. ‘Stop criterion’ results do not add to 100% as 7/27 children failing the BE OFC met > one criterion. c1/8 of a muffin contained 1.25 g of baked egg (0.2 g egg protein), mean (SD)
