Elaine Beller and colleagues from the PRISMA for Abstracts group provide a reporting guidelines for reporting abstracts of systematic reviews in journals and at conferences.
Systematic reviews are difficult to keep up to date, but failure to do so leads to a decay in review currency, accuracy, and utility. We are developing a novel approach to systematic review updating termed "Living systematic review" (LSR): systematic reviews that are continually updated, incorporating relevant new evidence as it becomes available. LSRs may be particularly important in fields where research evidence is emerging rapidly, current evidence is uncertain, and new research may change policy or practice decisions. We hypothesize that a continual approach to updating will achieve greater currency and validity, and increase the benefits to end users, with feasible resource requirements over time.
The Cochrane Collaboration is a global network whose aim is to improve health-care decision making through systematic reviews of the effects of health-care interventions. Cochrane systematic reviews are published in the Cochrane Database of Systematic Reviews within The Cochrane Library ( http://www.thecochranelibrary.com), and regularly updated as new evidence arises. Cochrane Reviews are undertaken by teams of volunteer authors, who have access to free training resources, reference texts and software for preparing and maintaining their review. Here we aim to describe the steps involved to undertake a new or update an existing Cochrane Review.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
