Unbiased, independent, critical assessment is an intrinsic part of all scholarly work, including the scientific process. Peer review is the critical assessment of manuscripts submitted to journals by experts who are not part of the editorial staff. Peer review can therefore be viewed as an important extension of the scientific process. Although its actual value has been little studied and is widely debated , peer review helps editors decide which manuscripts are suitable for their journals and helps authors and editors to improve the quality of reporting. iMedPub journals submits all its submitted manuscripts for outside review. The number and kinds of manuscripts sent for review, the number of reviewers, the reviewing procedures, and the use made of the reviewers’ opinions may vary in every iMedPub Journal.
