Abstract: 
Objectives:
- To test an extrapolation tool
- To debate methodological concerns around equity and systematic reviews

Description:
There is a need for guidance on how knowledge users can apply the results from Campbell and Cochrane reviews to disadvantaged groups. The question that these stakeholders have is really “In my setting/ population, will this intervention produce the same results as those from the systematic review and/or trials?”
We proposed to help researchers, practitioners, and policy-makers using Cochrane and Campbell reviews by giving them guidance on this –such as by applying a simple scale for groups of interest. We then conducted a pilot exercise using a checklist with Cochrane leaders. We are now revising the tool and developing testing scenarios; these scenarios are reflective of different settings and populations globally. In advance of the workshop, the tool will be applied by different stakeholders to our testing scenarios through online surveys.
• Introductions
• Short presentation
• Exercise: participants will apply the tool to scenarios (15 min)
• Breakout groups: discussion on experience with testing scenarios and checklist; participants will be asked to consider specific methodological issues related to the exercise.
• Report back.
• Wrap-up.
