The IEJ is a member of the Committee on Publication Ethics (COPE). COPE’s flowcharts and guidelines are approached in confronting any ethical misbehavior. The Journal also follows the guidelines mentioned in the Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals issued by the International Committee of Medical Journal Editors (ICMJE).


Authorship and Authors’ Responsibility

According to the Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals, released by the ICMJE, an “Author” is generally considered to be someone who concurrently meets all of the following conditions:

1-Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND

2-Drafting the work or revising it critically for important intellectual content; AND

3-Final approval of the version to be published; AND

4-Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation letter from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.

The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest statements, are properly completed. The corresponding author should respond to editorial queries throughout the submission and peer review process in a timely manner, and should cooperate with any requests from the journal after publication. In addition, IEJ does not allow multiple corresponding authors for one article; only one author should correspond with the editorial office and readers.


Submission declaration

Submission of a manuscript implies that the work described has not been published previously, that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out.


Conflict of Interest/Competing Interests

Authors, reviewers, and editors must declare potential competing interests or interests that may be perceived as such as they relate to the research. A competing interest may relate to a person or an entity and may be of a financial, non-financial, political, religious, ideological, professional or personal nature.

Authors/reviewers may find the following useful resources to refer to for more information on Conflict of Interest policies, existing codes of practices and more general good practice in relation to journal publication ethics:

View the guidelines published by the International Committee of Medical Journal Editors (ICMJE).

View the Common Standard for Conflict of Interest Disclosure published by Center for Science in the Public Interest.


Disclosure of Funding Sources

The authors may request to identify who provided financial support for the conduct of the research and to briefly describe the role of the sponsor(s), if any, in the “methods and materials” section.


Use of inclusive language

Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Articles should make no assumptions about the beliefs or commitments of any reader, should contain nothing which might imply that one individual is superior to another on the grounds of race, sex, culture or any other characteristic, and should use inclusive language throughout. Authors should ensure that writing is free from bias, for instance by using “he or she”, “his/her” instead of ”he” or “his”, and by making use of job titles that are free of stereotyping.


Human and Animal Rights

Studies that involve human beings must adhere to the principles of the “Declaration of Helsinki” (The Code of Ethics of the World Medical Association). The trials must registered in ethical committee of the research centers or Universities where the study was carried out; the “Methods and Materials” section should include a statement that the study approved by an appropriate ethics committee too.

Randomized clinical trials should be registered in appropriate trial registries (i.e. Clinical or Iranian Registry of Clinical Trials ) approved by the WHO and their registration number should be mentioned in the title page.

Where human subjects are used, the informed consent explaining the nature of the procedure and possible discomforts and risks should be obtained from all patients who participated in the experimental investigation and subjects should be able to freely reject participation.

If animals are used, a statement protocol approval by the institutional animal care and use committee must be included. All animal experiments should comply with the ARRIVE guidelines.

Manuscripts may be rejected if the Editor considers that the research has not been carried out within an appropriate ethical framework. In rare cases, Editor may contact the ethics committee for further information.


Reporting clinical trials

Randomized controlled/clinical trials should be presented according to the CONSORT guidelines. At manuscript submission, authors must provide the CONSORT checklist accompanied by a flow diagram that illustrates the progress of patients through the trial, including recruitment, enrollment, randomization, withdrawal and completion, and a detailed description of the randomization procedure. The CONSORT checklist and template flow diagram are available online.


Informed Consent

All patients and volunteers in a research project should be carefully informed about the aims of the trial and any possible side effects of the drugs/materials and interventions. Written informed consent from the participants or their legal guardians is compulsory for any such studies. The IEJ reserves the right to request the related documents. Articles that require informed consent should acknowledge related statements in the “Methods and Materials” section.


Originality and Duplicate Publication

Manuscripts under review or published by other journals will not be accepted for publication in IEJ, and articles published in this journal are not allowed to be reproduced in whole in any type of publication without permission of the IEJ. Figures and tables can be used freely if original source is verified according to Creative Commons Non-Commercial License. It is mandatory for all authors to resolve any copyright issues when citing a figure or table from a different journal that is not open access.


Post-publication discussions

The post-publication discussion is available through “letter to editor”. If any readers have a concern on any published articles, they can submit “letter to editor” within 3-months after publication.


Handling the complaints and appeals

Authors/reviewers/readers may register complaints and appeals in a variety of cases as follows: falsification, fabrication, plagiarism, duplicate publication, authorship dispute, conflict of interest, un-ethical treatment of animals, informed consent, bias or unfair/inappropriate competitive acts, copyright, stolen data, defamation, and legal problem. If any individuals or institutions wish to inform these cases, they should send a letter to editor.

For the complaints or appeals, concrete data with answers to all factual questions (who, when, where, what, how, why) should be provided. To handle complaints and appeals, IEJ follows the flowchart provided by the Committee of Publication Ethics available from:


Data sharing and reproducibility

Data sharing is the practice of making data used for scholarly research available to other investigators via deposit raw data/analysed data to a public repository i.e. Dryad for clarifying the reproducibility of the results. This is a function of research/innovation community’s willingness to share, build, replicate, and expand the current knowledge base.

IEJ strongly recommends authors to share data to build public trust. IEJ encourages the authors to announce the related code. If the data is already a public one, its URL site or sources should be disclosed.

IEJ would like to follow ICMJE guidelines for scholarly journal practice and specially the ICMJE data sharing policy. Manuscripts submitted to IEJ reporting results of clinical trials is better to contain a data sharing statement that includes the 'conditions of consideration for publication of a clinical trial report', as delineated by ICMJE.

However, as a new requirement for submission the manuscript in IEJ, clinical trials that began enrollment from January 1, 2019 must include a data sharing plan in the trial's registration.


Process to Manage Research Errors and Publication Misconduct

The IEJ will continuously work towards observing publication misconducts such as plagiarism, redundant (duplicate) publication, falsification, fraudulent or fabricated data, changes in authorship, undisclosed conflict of interest, ethical problem with a submitted manuscript, a reviewer who has appropriated an author’s idea or data, complaints against editors, and etc. When the IEJ faces suspected cases of research and publication misconduct, the resolving process will be followed by guidelines provided by the "Committee on Publication Ethics (COPE)". The complete guidelines appear on COPE website:


Retraction Policy

The IEJ uses the COPE flowchart for retraction of a published article to determine whether a published article should be retracted.
