Competing Interests

Nicholas Wald jointly holds European and Canadian patents (EU1272220 priority date 10 April 2000) for a combination pill for the prevention of cardiovascular disease (pending in USA) and together with David Wald has an interest in its development. Cipla provided the pills used in the trial free of charge. This does not alter the authors’ adherence to all the PLoS ONE policies on sharing data and materials.
