Intervention not reported

Antibiotic prescriptions (number of courses/person/year) **Corticosteroids not meta‐analysed · adults (> 18 years of age) with either COPD or recurrent acute exacerbations of chronic bronchitis

The intervention may leads to higher antibiotic prescriptions (number of courses/person/year)… (low certainty).
