Figure 2From: The prevalence of increased serum IgE and Aspergillus sensitization in patients with COPD and their association with symptoms and lung functionPrevalence of increased serum IgE, Aspergillus hypersensitivity, and ABPA in patients with COPD. The prevalence of increased serum IgE, Aspergillus hypersensitivity, and allergic bronchopulmonary aspergillosis in patients with COPD was shown with a disproportional Venn diagram. Definition of abbreviations: IgE(+): increased serum IgE, IgE(−): normal serum IgE, AH: Aspergillus hypersensitivity, ABPA: allergic brochopulmonary aspergillosis.Back to article page
