The goal of the web-based activity is to gather data that will permit us to establish generalizable estimates of the stability of effects that systematic reviewers and users of systematic reviews expect from the GRADE approach to be useful for decision making. The project is a collaboration between the Austrian Cochrane Branch (located at Danube University, Krems, Austria) and RTI International, USA.
