Resources for documenting your search
We recommend that you document your search strategies using a tool with which you're comfortable. Commonly used tools include desktop or web-based word processors and spreadsheet software. Web-based software (e.g. MUSC Box, Google Docs or Google Sheets) should be considered for collaborative projects.
If you are doing a systematic review, you will need to include a PRISMA Flow Diagram in your published manuscript.
