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.

Easy access to critically appraised systematic reviews

Shea and colleagues (1) are right to highlight the need for users of systematic reviews to be critical and look carefully at methodological quality.

However, readers may be interested to learn that DARE (the Database of Abstracts of Reviews of Effects) uniquely provides easy access to over 4500 abstracts of quality assessed and critically appraised systematic reviews.

For each included review, an abstract is written by experienced researchers with expertise in evidence synthesis and systematic review. The abstract summarises the review methods, results and conclusions together with a critical assessment of the overall quality. To assist busy decision makers, each abstract now starts with a 60 word ‘bottom line’ explaining what the review was about, what it found and whether the review conclusions are reliable.

DARE has become a key resource for health professionals, policy makers and researchers around the world. It covers a broad range of health and social care topics and can be used for answering questions about the effects of interventions, as well as for developing guidelines and policy making.

The database is updated monthly, is free to access via the CRD website (www.crd.york.ac.uk/) and is also available via the Cochrane Library.
