Making the Critical Appraisal for Summaries of Evidence (CASE) for evidence-based medicine (EBM): critical appraisal of summaries of evidence

While the reviewers agreed on worksheet responses for most questions, variation occurred in how the raters navigated the tool and interpreted some of the questions. Further validation of the form by other groups of users should be investigated.
