When a scientific review is performed, no matter how well founded or thorough it is, its value is limited by the verbosity of what the reviewer actually provides in terms of comments to the authors and editor. An excellent review will not only state the reviewer’s observations, impressions, and recommendations, especially with respect to the three issues described above, but also detail his or her basis for all recommendations. Unfortunately, this is where many reviewers fall short, and it becomes problematic for both editors and authors. For editors, it is not uncommon to receive conflicting reviews, which they resolve through a careful assessment of the basis of the recommendations made by the conflicting reviewers and possibly the invitation of a third reviewer. When such a basis is not adequately detailed, they have insufficient insight to do this. For authors, detailed feedback is required to make constructive changes to improve their manuscripts in response to the concerns raised.
