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.

Clarification of methodology

We wish to clarify the selection of countries we included in our analysis of drowning deaths. To ensure statistical stability in the calculation of percentages, we included those countries with 20 or more reported unintentional drowning deaths, not more than 20 as indicated in the methodology.
