ACADEMIC STANDARDS
IJO follows a stringent peer review policy. Each article is first evaluated by the editor-in-chief for the originality and scientific rigor of its research. If it passes this first test, the editor-in-chief assigns at least two peer reviewers, to determine whether it meets the rigorous scientific standards, whether it requires revisions, or whether it should be rejected. Only original material that meets IJO editorial standards will be published.
