Corrections may be made to a published article with the authorization of the editor of the journal. Editors will decide the magnitude of the corrections. Minor corrections are made directly to the original article. However, in cases of major corrections, the original article will remain unchanged, while the corrected version will also be published. Both the original and corrected version will be linked to each other. A statement indicating the reason for the major change to the article will also be published. When necessary, retraction of articles will be done according to COPE retraction guidelines
