In this article the ‘Competing Interests’ statement was incomplete and should have included ‘M.K.H. reports consulting fees from Boehringer Ingelheim, GSK and AstraZeneca. She also reports research support from Novartis and Sunovion. GSK also supported publication of this article.’ The original article has been corrected.
