Vienna meeting on Overviews

The following meeting took place on 8 October 2015 in Vienna, following the Cochrane Colloquium, and was attended by 50 participants. The meeting was organised by Joanne McKenzie, Steve McDonald, Carole Lunny, Lisa Hartling and Michelle Foisy.

The aims of the meeting were to discuss key methods issues for overviews of systematic reviews, including:

  • what we know about the methods for overvews
  • where there is uncertainty in the methods
  • what guidance reviewers are seeking
  • where empircal evidence is required
  • what research needs to be prioritised

The intended outcomes were to explore the potential for a group dedicated to methods research in overview, and to promote international collaborations.
