Edited or whole manuscript is presented to the associate editors for preliminary evaluation within one working day.

The associate editors appoint two referees from among the members of the arbitration committee who have the work related to the branch of the manuscript, provided that the authors do not serve in the same institution on the manuscripts decided to be evaluated. In order to ensure authorship and referee privacy, all personal and communication information of the author or everything describing the authors of the manuscript are closed by editing service for review by the double-blind method. The blind copies prepared for the referees are sent to them by the editing services.

For the experimental, clinical and drug human studies, approval by ethical committee and statement on the adherence of the study protocol to the international agreements (Helsinki Declaration revised 2013 are required. In experimental animal studies, the authors should indicate that the procedures followed were in accordance with animal rights (Guide for the care and use of laboratory animals, and they should obtain animal ethic committee approval. The Ethic Committee approval document should be submitted to the Turkish Journal of Endocrinology and Metabolism together with the manuscript.

The approval of the ethic committee, statement on the adherence to international guidelines mentioned above and that the patients` informed consent is obtained should be indicated in the `Material and Method` section and is required for case reports whenever data/media used could reveal identity of the patient. The declaration of the conflict of interest between authors, institutions, acknowledgement of any financial or material support, aid is mandatory for authors submitting manuscript and the statement should appear at the end of manuscript.

We use "iThenticate" to screen all submissions for plagiarism before publication.

Plagiarism: To re-publish whole or in part the contents of another author's publication as one's own without providing a reference.

Fabrication: To publish data and findings/results that do not exist.

Duplication: Use of data from another publication, which includes re-publishing a manuscript in different languages without citing.

Salamisation: To create more than one publication by dividing the results of a study preternaturally.

We disapproval upon such unethical practices as plagiarism, fabrication, duplication, and salamisation, as well as efforts to influence the review process with such practices as gifting authorship, inappropriate acknowledgements, and references. Additionally, authors must respect participant right to privacy. On the other hand, short abstracts published in congress books that do not exceed 400 words and present data of preliminary research, and those that are presented in an electronic environment are not accepted pre-published work.

Authors in such situation must declare this status on the first page of the manuscript and in the cover letter. (The COPE flowchart is available at:
