There are several digital tools available to assist researchers with question formulation or other parts of the systematic review.  For question formulation, some researchers use visualization tools like Gephi or VOSviewer.  SWIFT-Review is an option for text mining purposes.  For citation management, RefWorks, Endnote, Mendeley, and Zotero are helpful.  See the Citation Management LibGuide.  For managing data, most systematic reviews are managed with Covidence software.  More information on Covidence can be found on both our Systematic Review LibGuide and our Covidence LibGuide.
