PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

The original paper states a 1:1 allocation ratio between intervention and control arms, which is incorrect. The planned allocation ratio used in the trial was 2:1 intervention:control. 

The editorial office have advised that this technical correction is posted as a comment.
