About this example
This is the most widely used PRISMA 2020 template: a new systematic review whose searches covered bibliographic databases and trial registers only.
PRISMA 2020 recommends reporting the number of records from each database rather than only a total, and listing the reasons full-text reports were excluded with a count for each. Both are shown here, and the numbers down the diagram add up.
