How much of a review will the manuscript author see?
The only part of a review an author will ever see is the “Comments to author” section of a review. Other information, such as "Comments to editor" or the rating scale questions, will NOT be seen by the reviewer.
The journal admin user can add/remove the “Comments to author” question from your reviewer feedback form by going to the “Settings” journal tab, clicking “Reviewer feedback form”, toggling the switch next to “Comments to author”, and then saving the changes to the journal.
