Comparison of means between cases and controls showed a mean total IgE level of 734.7 kU/L (n = 798, median = 271.0, SEM = 51.4) versus 122.1 kU/L (n = 806, median = 50.0, SEM = 8.9) in inhalant allergy, respectively (p < 0.001), and 755.2 kU/L (n = 77, median = 252.0, SEM = 152.7) versus 142.1 kU/L (n = 223, median = 52.0, SEM = 21.1) in food allergy, respectively (p < 0.001). Here, IGHE is linked to food allergy.
