Positive skin-prick test response (≥2+): 108/1886 for wild-type and genetically modified (GM) potato. A/H ratio: the ratio of the size of the wheal induced by allergen on allergic skin-prick test to that induced by histamine; N: number of subjects positive to skin-prick test for wild-type and GM potato; sIgE: prevalence of serum specific IgE antibody to wild-type and GM potato (number of subjects with positive serum specific IgE/number of subjects tested in each response group according to the skin-prick test using potato extract). | |||||||||||
