The patients were compared in terms of the number of exacerbations, dose of oral corticosteroids (OCS), asthma control test (ACT), forced expiratory volume in 1 second (FEV1), forced vital capacity, fraction of exhaled nitric oxide (FeNO), number of blood eosinophils, and total immunoglobulin E (IgE). Here, IGHE is linked to asthma.
