PRISMA-S has been submitted for publication. We are hoping that it will be formally published later in 2020. > Within this fork, the PRISMA-S checklist is available not only as an Excel, Word, or PDF, but also as an R Markdown file. I hold a copyright for the R Markdown presentation only. Licensing terms unknown, please contact the original authors. The draft version of PRISMA-S was open for comment until June 15, 2019. We completed compiling, synthesizing, and addressing the over 350 comments and suggestions we received from the tremendously supportive and engaged community of information specialists, librarians, and systematic review methodologists. We greatly appreciate the global interest in PRISMA-S as well as the significant time and effort many have volunteered to improve PRISMA-S. The PRISMA-S Extension project began in 2015. The Delphi process and consensus conference took place in 2016. The draft of the PRISMA-S Checklist and Explanation & Elaboration documents are currently in review. The need for a specific extension for search reporting was made clear through many studies regarding the irreproducibility of searches, including in this study by Jonathan Koffel and Melissa Rethlefsen: - Koffel, J. B. and M. L. Rethlefsen (2016). "[Reproducibility of Search Strategies Is Poor in Systematic Reviews Published in High-Impact Pediatrics, Cardiology and Surgery Journals: A Cross-Sectional Study][1]." PLoS One 11(9): e0163309. This study built on and confirmed work by Rethlefsen, Farrell, Trazsko-Osterhaus, and Brigham and Koffel: - Koffel, J. B. (2015). "[Use of recommended search strategies in systematic reviews and the impact of librarian involvement: a cross-sectional survey of recent authors][2]." PLoS One 10(5): e0125931. - Rethlefsen, M. L., et al. (2015). "[Librarian co-authors correlated with higher quality reported search strategies in general internal medicine systematic reviews][3]." J Clin Epidemiol 68(6): 617-626. Rethlefsen and Koffel teamed up with Shona Kirtley to develop the [protocol for the PRISMA-S extension][4], initially published on the EQUATOR Network web site. Data from the Delphi survey process, the consent cover letters, the survey tools, and more will be available on the OSF site for PRISMA-S.
