To identify independent risk factors related to asthma control, variables that have significant differences between three groups of asthma control including basic characteristics (BMI, SNOT22 score, and RQLQ score), blood examination (blood eosinophil%, blood eosinophil counts, and serum total IgE), and pulmonary indicators (sputum total IgE, sputum Phadiatop, sputum Eos%, FeNO, FEV1%pred, FEV1/FVC, MEF75, MEF50, MEF25, and MEF75/25) were performed with ordinal logistic regression analysis. The gene discussed is IGHE; the disease is asthma.
