Now that you've finished collecting and analyzing the data, it's time to write and disseminate the results via a publication or presentation. All evidence synthesis projects should follow the appropriate reporting guidelines, if one exists. The primary reporting guideline used today is PRISMA, or the "Preferred Reporting Items for Systematic reviews and Meta-Analyses."
Important distinction: reporting guidelines do not teach you how to do evidence synthesis! Instead, they tell authors what to report, where and how to report it, and why reporting that item is recommended. Therefore, manuscripts should never say "This study was performed according to the PRISMA Guidelines." Better wording might be "The results of this review are being reported according to the PRISMA 2020 Guidelines."
