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.

Correction of typographical error in statistical methods

Following publication of this article, we noticed a significant typographical error in the statistical section that needs to be corrected. Please note that specificity of the test was determined according to the following formula:

Specificity = 1 - false-positives/total controls

The same results are obtained if the following formula is used:

Specificity = true negatives/total controls
