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 info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

After the work [1] was published we realized a minor error with regard to contents.

In Table 1, there were two studies by the author Cummings. The first study was published in 1998 with the drug alendronate [2]. The second study published by Cummings in 2009 involved denosumab [3]. During the editorial process, we submitted the description of study and baseline characteristics to be identical for 1998 study and the 2009 study, which they are not. The 2009 study published by Cummings involved denosumab versus placebo, was a 3 year study, that was international in 182 sites, with baseline age of 72.3(5.2) (mean(SD)), the years since menopause as an inclusion criteria and baseline years since menopause were not reported, baseline BMD was also not reported, and the percent of prior vertebral fracture was 23.6%. The authors regret any confusion by our editorial error. The statistical analysis was not affected.
