Abstract: 
Objectives:
– To discuss the issues involved in deciding to summarize multiple interventions using an overview or an intervention review
– To identify and explore key unresolved issues

Description:
This is the first in a series of three workshops. Cochrane authors who wish to compare the effectiveness of two or more interventions for the same condition now have two options. They can produce an overview synthesizing the results of all relevant Cochrane intervention reviews, or they can produce an intervention review with a broad enough scope to cover all of the relevant interventions. This workshop will explore the strengths, weaknesses and tradeoffs of these two approaches with special reference to issues such as searching, data extraction, evaluating risk of bias, approaches to data synthesis, and interpretation of findings. The material presented will draw on the results of a special meeting on this topic organized by the Cochrane Comparing Multiple Interventions Methods Group in March 2011. Participants will be encouraged to share their experiences and perspectives on this rapidly developing area of methodology within the Collaboration and to help identify key issues to be resolved in moving forward.
