PRISMA stands for Preferred Reporting Items for Systematic Reviews and Meta-Analyses. It is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses.
They have created the following PRISMA statements for many areas of the Systematic Review and Meta-Analysis. You use these STANDARDS when creating and conducting the synthesis research (and you reference them in your methods section of the protocol and the full review!).
FYI: The JBI Methodology is built off the PRISMA statements--so before submitting for peer-review, ENSURE YOU HAVE ADDED REQUIRED PHRASES TO EACH SECTION OF YOUR PROTOCOL OR FULL REVIEW. You will save yourself a lot of re-writing.
There are many more PRISMA standards for different types of systematic reviews. Check out the website listed above.
