Collaboration's impact on research reports and the value of systematic reviews
The Lancet has announced it will ask authors of research reports submitted after 1 August 2010 to report their own, up-to-date systematic review or cite a recent systematic review done by others. Please see the editorial here. This is important recognition of systematic reviews as a key element in understanding the findings from all new research.
The Lancet's decision was infl uenced by work done over the last 12 years at the UK Cochrane Centre, together with Iain Chalmers of the James Lind Initiative. We hope this policy will lead to even greater prominence of systematic reviews across the research literature.
