Publication Ethics
Turkish Journal of Gastroenterology aims to adhere to the guidelines and core practices set forth by several organizations, including the Committee on Publication Ethics (COPE) guidelines, the Principles of Transparency and Best Practice in Scholarly Publishing (joint statement by COPE, DOAJ, OASPA, WAME), and Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals by ICMJE.  These guidelines and recommendations are designed to promote transparency, integrity, and best practices in scholarly publishing. By adhering to these standards, the journal aims to ensure that the research it publishes is of high quality and meets the ethical standards of the scientific community.

Medical research involving human subjects including research on identifiable human material and data should follow the WMA Declaration of Helsinki amended in 2013 to provide guidance on issues such as obtaining informed consent from participants, protecting their privacy and confidentiality, and avoiding harm to study participants.  

Turkish Journal of Gastroenterology also adheres to the WAME’s Recommendations on Publication Ethics Policies for Medical Journals. These recommendations provide guidance on how to handle conflicts of interest, how to deal with suspected research misconduct, and how to ensure the integrity and transparency of the peer review process. By following these recommendations, the journal helps to ensure that the research it publishes meets the highest ethical standards.

Authors are advised to use EASE Ethics Checklist for Authors to ensure that their manuscripts comply with ethical standards and practices. 

Human and animal rights 
All research involving human subjects, medical records, or human tissues must be reviewed and approved by a reviewer board, such as an institutional review board (IRB) or ethics committee, before it is conducted. The name of the ethics committee that reviewed and approved the research, as well as the ethics committee approval number and date, should be included in the Methods section of the manuscript when it is submitted for publication. Additionally, the journal may require authors to provide a copy of the ethics committee approval as part of the manuscript submission process. This is to ensure that the research has been properly reviewed and approved, and to allow the journal to verify that the research meets the ethical standards required for publication. 

If a study is exempted from the ethics committee approval, the authors must present a statement from the ethics committee explaining the reason for the exemption. This is to ensure that the research was reviewed by an ethics committee and that the decision to exempt the study was made in accordance with the relevant guidelines and regulations. 

If a manuscript is submitted to Turkish Journal of Gastroenterology without ethics committee approval, the journal will review the manuscript according to the COPE’s Research, Audit and Service Evaluations guideline. This guideline provides guidance on how to handle manuscripts that do not have ethics committee approval, and allows the journal to assess the risks and potential ethical concerns associated with publishing the research.

If the journal determines that the lack of ethics committee approval is a significant concern, the manuscript may be rejected after editorial review. This is to ensure that the journal maintains high ethical standards and only publishes research that has been properly reviewed and approved by an ethics committee.

For studies involving animals, it is required to obtain approval of research protocols from an ethics committee. The ethics committee should review the research protocols to ensure that they are in compliance with relevant guidelines and regulations, such as the Guide for the Care and Use of Laboratory Animals (8th edition, 2011) and the International Guiding Principles for Biomedical Research Involving Animals (2012). These guidelines provide detailed information on how to conduct research involving animals in an ethical and humane manner, and are widely recognized as the standard for such research.

Authors should provide detailed information on the ethical treatment of animals in their manuscript, including the measures taken to prevent pain and suffering. They can use the ARRIVE checklist, which is designed to help authors provide this information in a clear and comprehensive manner.

In addition to the ethical treatment of animals, authors should also provide information on the measures taken to prevent pain and suffering. This is to ensure that the research is conducted in a humane manner, and to allow readers to verify that the research meets the relevant ethical standards.

Informed consent 
For manuscripts concerning research involving human subjects, it is required to include a statement indicating that written informed consent was obtained from all participants.Informed consent should be documented in writing, and a copy of the informed consent form should be retained by the researchers for future reference.

In the case of research involving children under the age of 18, the parent or guardian of the child must provide informed consent on behalf of the child. This is because children are considered to be a vulnerable population and may not have the capacity to fully understand the risks and benefits of participating in research.

If the manuscript reports the findings of a survey or interviews, the author must confirm that the participants gave their informed consent to participate in the study and for their personal details to be recorded if that is the case. If quotations or other attributable statements are included, these must be deidentified, or the manuscript must state that the person agreed to be named in the manuscript.

Information on informed consent should be provided in the Methods section of the manuscript, along with any other relevant details about how the research was conducted.

It is the responsibility of the authors to protect the anonymity of study participants, and to ensure that the research is conducted in a way that respects their privacy and confidentiality. This is especially important for photographs that may reveal the identity of patients, as the publication of such photographs without proper consent could potentially violate the rights of the individuals depicted.

To protect the anonymity of patients in photographs, the authors should obtain signed releases from the patients or their legal representatives. These releases should indicate that the patients have given their consent for the publication of the photographs, and should specify any restrictions or conditions on the use of the photographs. Information on the publication approval for photographs should be provided in the Methods section of the manuscript.

Plagiarism and Ethical Misconduct
All submissions are screened by a similarity detection software (Crossref Similarity Check Powered by iThenticate) multiple times during the peer-review and/or production processes.
 
When you are discussing others' (or your own) previous work, make sure that you cite the material correctly in every instance.
 
Authors are strongly recommended to avoid any form of plagiarism and ethical misconduct that are exemplified below.

Citation manipulation: The practice of manipulating the number of citations received by an author, journal, or other publication through various means, such as self-citation, excessive citation of articles from the same journal, or the inclusion of honorary citations or citation stacking. 
Self- plagiarism (text-recycling): The practice of using overlapping sections or sentences from the author's previous publications without properly citing them. This is considered to be a form of plagiarism, as it involves using someone else's work (in this case, the author's own work) without proper attribution.
Salami slicing: The practice of using the same data from a research study in several different articles. This is considered to be unethical, as it involves reporting the same hypotheses, population, and methods of a study in multiple papers.
Data Fabrication: The addition of data that never occurred during the gathering of data or experiments. This is considered to be a form of research misconduct, as it involves presenting false or misleading information as if it were real data.
Data Manipulation/Falsification: The practice of manipulating research data with the intention of giving a false impression. This can include manipulating images, removing outliers or "inconvenient" results, changing data points, and other forms of manipulation. This is also considered to be a form of research misconduct, as it involves presenting false or misleading information as if it were real data.
 
In the event of alleged or suspected research misconduct such as plagiarism, citation manipulation, or data falsification/fabrication, the Editorial Board will follow the appropriate COPE flowcharts to ensure that the allegations or suspicions are handled in a fair, transparent, and consistent manner.
