Starting in 2016, we have offered authors the option to publish the comments received from the reviewers and their responses alongside the paper. As we believe that transparency strengthens the quality of peer review, we are now moving to publish the exchanges between authors and reviewers for all research articles submitted from November 2022 onward and accepted for publication. Referees will still have the option to remain completely anonymous, to sign their reports, and/or to choose to be acknowledged by name as part of our reviewer recognition scheme.
