IGHE and Increased total eosinophil count: Furthermore, comparing the clinical data with membrane IgE-positive cells revealed that the number of membrane IgE-positive mast cells was also positively correlated with radiological severity of CRS (r = 0.470, p < 0.001; Figure 5B), peripheral blood eosinophilia (r = 0.327, p = 0.002; Figure 5C), and the total serum IgE level (r = 0.458, p < 0.001; Figure 5D).
