Abstract
The world is awash with information. For any question, the briefest of internet searches will throw up a range of frequently contradictory answers. This underlies increasing awareness of the value of systematic evidence synthesis—both qualitative and quantitative—by researchers, policy makers and the broader public. It is reflected in the continuing development of the Cochrane Collaboration (http://www.cochrane.org/), an international collaboration devoted to undertaking, publishing and promoting systematic evidence synthesis [2].
