After publication of this article [1], the authors reported that the manuscript incorrectly identifies the trial registration for this study. It identifies the associated trial registration as NCT01006967, which was a subsequent trial that was ongoing at the time of submission, as opposed to the correct trial registration NCT00810082 which is the study described in the manuscript.

The original article [1] has been updated.
