IGHE and Increased total eosinophil count: In the high-IgE group, the ages of the patients were significantly lower than that in the low-IgE group [21.0 (18.0, 28.0) vs. 32.0 (19.0, 50.0); P = 0.024]; the proportion of female patients was significantly lower than that in the low-IgE group (19.4% vs. 49.3%, P < 0.001); and the proportion of patients with eosinophilia was significantly higher than that of the low-IgE group (16.4.% vs. 1.5%; P = 0.006).
