What is Rayyan?

This research tool is used for filtering of citations from searches, and tracking decisions to include or exclude studies, with tags designating reasons for decisions and labels showing topics. Rayyan provides information the number of records screened, and records excluded with reasons for inclusion and exclusion. Blinding decisions by researchers can be turned on during the screening process, and turned off to resolve conflicts. Documenting these decisions by the authors ensures the transparency, clarity, and traceability of the selection process, and reinforces the robustness of review or scan.
