Erratum
Following publication of our article [1] we identified an error in Fig. 5, where results were inadvertently switched between morning and evening PEF responses. The corrected Fig. 5 is provided in this erratum. The PEF results provided in our original article text remain correct.
Morning and evening PEF response after 4 weeks of treatment (full analysis set). Adjusted for ‘treatment’, ‘period’, ‘patient’ and ‘baseline’. *p < 0.05 versus placebo Respimat®. PEF, peak expiratory flow
