Competing Interests

Members of the team have co-authored three of the included Cochrane reviews, [60,80,118] and also some of the trials included in these reviews, but they were not involved in the quality assessment of these studies. This does not alter the authors’ adherence to all the PLOS ONE policies on sharing data and materials.
