Covidence lets you select which collection of studies you would like to export. You can do this by using the Export studies tool, accessible from your Review dashboard.
Covidence will export the studies in RIS text format and provide you with a file that can be used in the following reference managers:
Any notes that you added during screening will be included in this export. For studies excluded at the full text review stage, Covidence will also export the reason for exclusion as a note.
When Covidence exports studies it ensures that links to references are maintained. This applies when you have more than one reference associated to a study.
