We thank the patients who took part in the RECORD study, without whose help this study would not have been possible. The MRC funded the central organisation of RECORD, and Shire Pharmaceuticals funded the drugs, which were cofunded and manufactured by Nycomed. However, the trial was conducted, analysed and reported independently of all funders. The Health Services Research Unit is core funded by the Chief Scientist Office of the Scottish Government Health Directorates. The views expressed here are those of the authors.
