Changes in participant total exacerbations, spirometry, and fractional exhaled nitric oxide (FeNO) over the course of the study. A Asthma exacerbations decreased significantly after therapeutic patient education (TPE). B–D Measurements were conducted on day 1 (visit 1) and after 6 months (visit 3) and 12 months (visit 4). Predicted forced expiratory volume in 1 s (FEV1) increased significantly and FeNO decreased over time. Medication adherence was calculated as the percentage of prescribed doses taken each week. *p < 0.05, **p < 0.01, ***p < 0.001
