Patient enrollment
We enrolled 145 children who fulfilled the eligibility criteria. Children who were lost to follow-up between the ages of 6 and 12 years (n = 22) were also excluded; therefore, the 123 remaining children were analyzed in this study (Figure 1).
Of the 123 children, 82 (67%) were male, 60 (49%) had previous anaphylaxis due to CM, 82 (67%) had eliminated CM completely, and the median CM-, and casein-sIgE values were 23.3 (7.0-66.4) kUA/L and 26.9 (5.8-72.0) kUA/L, respectively (Table 1).
