10 Such situations may arise when effect estimates are incompletely reported or because characteristics of studies (such as study designs, intervention types, or outcomes) are too diverse to yield a meaningful summary estimate of effect. The SWiM guideline is intended for use in systematic reviews examining the quantitative effects of interventions for which meta-analysis of effect estimates is not possible, or not appropriate, for a least some outcomes. This paper presents the Synthesis Without Meta-analysis (SWiM) reporting guideline. 7 This suggests widespread lack of familiarity and misunderstanding around the requirements for transparent reporting of synthesis when meta-analysis is not used and indicates the need for a reporting guideline. 9 Recent work highlights serious shortcomings in the reporting of narrative synthesis, including a lack of description of the methods used, lack of transparent links between study level data and the text reporting the synthesis and its conclusions, and inadequate reporting of the limitations of the synthesis.

We estimate that 32% of health related systematic reviews of interventions do not do meta-analysis, 6 7 8 instead using alternative approaches to synthesis that typically rely on textual description of effects and are often referred to as narrative synthesis. 5) However, PRISMA provides limited guidance on reporting certain aspects of the review, such as the methods for presentation and synthesis, and no reporting guideline exists for synthesis without meta-analysis of effect estimates. 2 Extensions are available for different approaches to conducting reviews (for example, scoping reviews 3), reviews with a particular focus (for example, harms 4), and reviews that use specific methods (for example, network meta-analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA ) statement, consisting of a 27 item checklist, was developed to facilitate improved reporting of systematic reviews. 1 Complete and transparent reporting of the methods and results of reviews allows users to assess the validity of review findings.

The SWiM guideline has been developed using a best practice approach, involving extensive consultation and formal consensusĭecision makers consider systematic reviews to be an essential source of evidence.

The SWiM items prompt users to report how studies are grouped, the standardised metric used for the synthesis, the synthesis method, how data are presented, a summary of the synthesis findings, and limitations of the synthesis The Synthesis Without Meta-analysis (SWiM) guideline is a nine item checklist to promote transparent reporting for reviews of interventions that use alternative synthesis methods Serious shortcomings in reviews that use “narrative synthesis” have been identified, including a lack of description of the methods used unclear links between the included data, the synthesis, and the conclusions and inadequate reporting of the limitations of the synthesis Systematic reviews of health related interventions often use alternative methods of synthesis to meta-analysis of effect estimates, methods often described as “narrative synthesis” 9Bruyere Research Institute, Ottawa, Canada.8Evidence for Policy and Practice Information and Coordinating Centre, University College London, London, UK.7Nuffield Department of Population Health, University of Oxford, Oxford, UK.6School of Psychology and Public Health, La Trobe University, Melbourne, Australia.5Nuffield Department of Primary Care Health Sciences, University of Oxford, Oxford, UK.4Centre for Guidelines, National Institute for Health and Care Excellence, London, UK.3Centre for Reviews and Dissemination, University of York, York, UK.2School of Public Health and Preventive Medicine, Monash University, Melbourne, Australia.1MRC/CSO Social and Public Health Sciences Unit, University of Glasgow, UK.Hilary Thomson, senior research fellow 1.Rebecca Ryan, senior esearch fellow 6,.Jamie Hartmann-Boyce, senior researcher 5,.Srinivasa Vittal Katikireddi, clinical senior research fellow 1,.Joanne E McKenzie, associate professor 2,.Mhairi Campbell, research associate 1,.
