We screened references (up to 2009) from the Cochrane Library, MEDLINE and EMBASE to identify systematic reviews relevant for SUPPORT, based on topic and methods documentation.][28][29][30] We extracted data, assessed review quality using a checklist and assessed evidence quality using GRADE. 31,32Based on earlier Abstracts in ‫,عريب‬ 中文, Français, Pусский and Español at the end of each article.Objective To describe how the SUPPORT collaboration developed a short summary format for presenting the results of systematic reviews to policy-makers in low-and middle-income countries (LMICs).Methods We carried out 21 user tests in six countries to explore users' experiences with the summary format.We modified the summaries based on the results and checked our conclusions through 13 follow-up interviews.To solve the problems uncovered by the user testing, we also obtained advisory group feedback and conducted working group workshops.Findings Policy-makers liked a graded entry format (i.e.short summary with key messages up front).They particularly valued the section on the relevance of the summaries for LMICs, which compensated for the lack of locally-relevant detail in the original review.Some struggled to understand the text and numbers.Three issues made redesigning the summaries particularly challenging: (i) participants had a poor understanding of what a systematic review was; (ii) they expected information not found in the systematic reviews and (iii) they wanted shorter, clearer summaries.Solutions included adding information to help understand the nature of a systematic review, adding more references and making the content clearer and the document quicker to scan.Conclusion Presenting evidence from systematic reviews to policy-makers in LMICs in the form of short summaries can render the information easier to assimilate and more useful, but summaries must be clear and easy to read or scan quickly.They should also explain the nature of the information provided by systematic reviews and its relevance for policy decisions.
