IGHE and Alzheimer disease: Measured parameters in both research groups were additionally evaluated using binomial logistic regression, resulting in the following: the percentage of eosinophils was significantly higher in the AD group than among controls (p = 0.012) (Figure 3); the IgE level was markedly higher in the AD group than in the control group (p < 0.001) (Figure 4); and miRNA-146a was considerably more expressed in the AD group than in the control group (p = 0.041).
