GM is the geometric mean level of serum IgE antibody in the positive samples.
Linear regression was used to compare serum IgE antibody to molecular allergens and whole allergen extracts.
The proportion of samples tested that did not have any molecular allergens with IgE ≥0.35 was 22% for milk, 42% for peanut, and 81% for wheat.
This statistical test was not performed because there were not enough positive samples.
Only 16 samples were tested because of a lack of serum.
