You can add notes as you work on your review. Click on the ‘Add Note’ button in the text field you are working on to write your note in the box that appears in the Context pane. You can insert tables and symbols in your notes.
Notes can be added to any section of the review and can be added or edited by any user. In Studies, notes can be added to each individual study, and in Analyses, to each analysis group (comparison).
To remove a note, just delete all the text. Currently it is not possible to remove notes globally, i.e. you have to remove notes one at a time.
