The use of multiple respiratory inhalers requiring different inhalation techniques has an adverse effect on COPD outcomes

Upon reviewing the article, the authors noticed an error in Figure 2 (page 65). The position of the markers for the incidence rate ratio for moderate/severe exacerbations and the odds ratio for average daily SABA dose (OR) in the initial figure were switched. The authors apologize for this error and have corrected the positions of both markers. The authors confirm that the values for both results in the figure legend and the corresponding text are correct and that the conclusion derived from this figure and the overall article do not change. The corrected version of Figure 2 is as follows:

Figure 2 Effect of similar versus mixed devices on primary and secondary COPD outcomes.

Notes: aIRR adjusted by antibiotic course, asthma diagnosis and paracetamol use. OR adjusted by baseline SABA and osteoporosis.
Abbreviations: CI, confidence interval; SABA, short-acting beta agonist.
