Comparison of changes in the clinical outcomes between patients who used inhalers for their airway diseases and those who did not use inhalers due to the absence of airway disease. (A) Chronic obstructive pulmonary disease (COPD) assessment test (CAT) score, (B) St. George’s Respiratory Questionnaire (SGRQ) score, (C) modified Medical Research Council (mMRC) dyspnea scale, (D) cough quality of life questionnaire (CQLQ) score, (E) EuroQol-5 dimension (EQ-5D) score, and (F) cough visual analogue scale (VAS) score. The analysis was carried out with 48 subjects excluding 11 patients who were lost to follow-up and 11 patients who used inhaler improperly. Increasing scores indicate worsening outcome in CAT, SGRQ, CQLQ, VAS, and mMRC. Decreasing scores indicate worsening outcome in EQ-5D. Differences between the two groups were tested using repeated measures analysis of variance (RM-ANOVA). Visit 1, baseline; Visit 2, 3-month follow-up. ap < 0.05.
