No differences were found in subjective improvement at 3 and 6 months, or in other results at 6 months (measured as the difference between results at 6 months and at baseline) such as lung function (FEV1 in mL and %), FeNO, asthma control based on the ACT score, emergency department visits, OCS use, and levels of blood eosinophils and IgE. Here, IGHE is linked to asthma.
