Correction
Following publication of this protocol [1], it was brought to the Editors’ attention in May 2014 that design of the study has been changed from a randomized controlled trial to a non-randomized study, and so will no longer follow the published protocol. For more information on the updated design and conduct of the study, please contact the corresponding author.
