The median interval between OFCs was 12.4\u00a0months and repeat OFCs were positive in 132 (54%) patients. One multivariate analysis model indicated that risk factors for a positive repeat OFC included cumulative dose (adjusted odds ratio [aOR]:0.58), anaphylaxis (aOR: 3.09), total serum IgE (aOR: 0.41), ovomucoid\u2010sIgE (aOR: 3.21), and age (aOR: 1.68) at the initial OFC. Another model indicated that the risk factors were cumulative dose (aOR: 0.59) and anaphylaxis (aOR: 3.41) at initial OFC and total serum IgE (aOR: 0.36), ovomucoid\u2010sIgE (aOR: 4.93), and age
