Ethics and consent
The journals published by University of Tehran follow the guidelines of the Committee on Publication Ethics (COPE).
Every submission reporting a research must include a statement to verify that ethics approval was sought for the study (or a statement that it was not required and why), including the name of the ethics committee(s) or institutional review board(s), the reference number/ID of the approval(s), and a statement that participants gave informed consent before participating. Even when a study has been approved by a research ethics committee or institutional review board, editors may ask authors for more detailed information about the ethics of the work. Also, research involving human subjects, human tissue, or human data must have been performed in accordance with the Declaration of Helsinki and must have been approved by an appropriate ethics committee. Submissions may be declined if the journals’ editors come to conclusion that a research has not been carried out within an appropriate ethical framework. The editors may also contact the institutions’ ethics committee for further information in certain cases.
Allegations of publication misconduct, both before and after publication will be carefully inspected and we reserve the right to contact authors' institutions, funders, or regulatory bodies if necessary. If a conclusive evidence of misconduct is noticed, proper steps will be taken to correct the scientific record, which may include supplying a correction or retraction.
Authors are assumed that they are aware of publication ethics, specifically with regard to authorship, dual submission, plagiarism, figure manipulation, competing interests and compliance with standards of research ethics. In cases of suspected misconduct, COPE standards and practices will be followed and advice from the COPE forum will be ascertained.
Retrospective ethics approval
If a study has not been granted ethics committee approval prior to commencing, retrospective ethics approval usually cannot be obtained and it may not be possible to consider the submission for peer review. The decision on whether to proceed to peer review in such cases is at the discretion of the journals’ editors.
Patient consent and confidentiality
Any item submitted to the journals published by University of Tehran that contains personal medical information about an identifiable living individual requires patient’s explicit consent before it can be published. Consequently; all studied patients are required to sign an informed consent form after reading the studies’ information sheet.
If consent cannot be obtained because the patient cannot be traced in a study, then publication will be possible only if the information can be sufficiently anonymized. Anonymization means that neither the person nor anyone else could identify the individual with certainty.
If the patient is dead the authors should seek permission from a relative (as a matter of courtesy and medical ethics). If the relatives are not contactable, the journals will balance the worthwhileness of the case, the likelihood of identification, and the likelihood of offence in decision to publish a submitted paper.
Images such as x-rays, laparoscopic images, ultrasound images, pathology slides, or images of undistinctive parts of the body may be used without consent so long as they are anonymized by the removal of any identifying marks and are not accompanied by text that could reveal the patients’ identity.
Research involving animals
Experimental research on vertebrates or any regulated invertebrates must comply with institutional, national, or international guidelines, and where available should have been approved by an appropriate ethics committee. The Basel Declaration outlines fundamental principles to adhere when conducting research on animals and the International Council for Laboratory Animal Science (ICLAS) has also published ethical guidelines.
For experimental studies involving client-owned animals, authors must also document informed consent from the client or owner and adherence to a high standard (best practice) of veterinary care.
Based on the ICMJE recommendations a clinical trial is defined as “any research project that prospectively assigns people or a group of people to an intervention, with or without concurrent comparison or control groups, to study the cause-and-effect, relationship between a health-related intervention and a health outcome.”
In agreement with the ICMJE’s recommendations, all journals published by University of Tehran will not consider reports of clinical trials unless they were registered prospectively before recruitment of any participants.
As a condition of consideration for publication, journals published by University of Tehran require registration of all trials in a public registry of trials. The trial registration number and the date of registration should be included in the last line of the submission abstract.
Standards of reporting
Authors are encouraged to use the relevant research reporting guidelines for the study type provided by the EQUATOR Network when preparing their manuscript. Authors should adhere to these guidelines when drafting their manuscript, and peer reviewers will be asked to refer to these checklists when evaluating such studies. This will ensure that the authors have provided enough information for editors, peer reviewers, and readers to understand how the research was performed and to judge whether the findings are likely to be reliable.
The key reporting guidelines are:
- Randomized controlled trials (RCTs): CONSORT guidelines
- Systematic reviews and meta-analyses: PRISMA guidelines and MOOSE guidelines
- Observational studies in epidemiology: STROBE guidelines
- Quality improvement studies: SQUIRE guidelines
- Qualitative research: SRQR or COREQ
Authors are requested to include full information about the applied statistical methods and measures in their research, including justification of the appropriateness of the statistical test used (see the SAMPL guidelines for more information). Reviewers will be asked to check the statistical methods, and the submission may be sent for statistical review by specialists if considered necessary. The editors may also consult a specialist in the field of methodology.
This journal encourages authors to share the data and any other material associated with methodology and the results of the submitted articles, in an appropriate public repository, or as open access supplementary to the article. In line with ICMJE recommendations, a data sharing statement is required for manuscripts reporting the results of clinical trials, on whether and how the data will be available. For more information, please consult ICMJE recommendations (http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial registration.html#two)
A competing interest is anything that interferes with, or could reasonably be perceived as interfering with, the full and objective presentation, peer review, editorial decision-making, or publication of research or non-research articles submitted to the journals published by University of Tehran.
A competing interest exists when professional judgment concerning a primary interest (such as patients’ welfare or the validity of research) may be influenced by a secondary interest (such as financial gain,—employment, consultancies, stock ownership or options, honoraria, patents, and paid expert—testimony or personal relationship). There is nothing unethical about a competing interest but it should be acknowledged and clearly stated. All authors must declare all competing interests in their covering letter and in the “competing interests” section upon submission. Where authors have no competing interests, the statement should read “The author(s) declare(s) that they have no competing interests with regards to authorship and/or publication of this article.” The Editor may ask for further information relating to competing interests.
Editors and reviewers are also required to declare any competing interests and will be excluded from the peer review process if a competing interest exists.
The policy of University of Tehran is that none of the journals’ editors should have any financial relationship with any biomedical company.
Declaring all potential competing interests is a requirement and is integral to the transparent reporting of research. Failure to declare competing interests can result in immediate rejection of a manuscript. If an undisclosed competing interest comes to light after publication, University of Tehran will take action in accordance with COPE guidelines and issue a public notification to the community.
Competing interests can be financial or non-financial, professional, or personal. Competing interests can arise in relation to an organization or a person.
Financial competing interests
Financial competing interests include (but are not limited to):
- Receiving reimbursements, fees, funding, or salary from an organization that may in any way gain or lose financially from the publication of the manuscript, either now or in the future.
- Holding stocks or shares in an organization that may in any way gain or lose financially from the publication of the manuscript, either now or in the future.
- Holding, or currently applying for patents relating to the content of the manuscript.
- Receiving reimbursements, fees, funding or salary from an organization that holds or has applied for patents relating to the content of the manuscript.
Non-financial competing interests
Non-financial competing interests include (but are not limited to) political, personal, ideological, academic, and intellectual competing interests.
Authors from pharmaceutical companies, or other commercial organizations that sponsor clinical trials, should declare these as competing interests on submission. They should also adhere to the Good Publication Practice guidelines for pharmaceutical companies (GPP2), which are designed to ensure that publications are produced in a responsible and ethical manner. The guidelines also apply to any companies or individuals that work on industry-sponsored publications, such as freelance writers, contract research organizations and communications companies. University of Tehran will not publish advertorial content.
An 'author' is generally considered to be someone who has made substantive intellectual contributions to a published study.
The Journal recommends that authorship be based on the following 4 criteria:
- Substantial contributions to the conception or design of the work or the acquisition, analysis or interpretation of data.
- Drafting the work or revising it critically for important intellectual content.
- Final approval of the version published.
- 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.
In addition to being accountable for the parts of the work the authors have done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their coauthors. All those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors.
Participation solely in the acquisition of funding, gathering of the data, technical help, writing assistance and general supervision of the research group does not warrant authorship. Those individuals who do not meet all four criteria should appear in the “Acknowledgments” section.
The individuals who provided assistance to the submitted work, who do not meet all four criteria of authorship, should be recognized by listing their names and contribution in the “Acknowledgments” section. The authors have to guarantee that anyone named in the “Acknowledgements” section has granted its clearance for permission to be listed for the stated contributions towards the work.
Financial and material support should also be acknowledged. All sources of grant and other support for the project or study, including funds received from contributors, institutions and commercial sources are required to be reported. Consultancies and funds paid directly to investigators must also be listed. The involvement of scientific (medical) writers or anyone else who assisted with the preparation of the manuscript content should be acknowledged, along with their source of funding, as described in the European Medical Writers Association (EMWA) guidelines.
Author information is published by the journals so that the authors and their institutes be recognizable for the scientific community. Author information is also used to retrieve records in databases and bibliographic indexes, and yet many databases either do not include or do not list all author information. We recognize that some authors have multi-part first, middle or last names and that some authors do not have a middle name, but a part of their first or last name has been used previously to provide a middle name initial in another publication. It is the policy of the journals published by University of Tehran to publish author information, including their names and affiliations in the same format supplied by the corresponding author upon submission. To ensure that publications have correct author information, to avoid any errors regarding how a certain author name should be spelled or supplied to bibliographic indexes and databases and to keep changes in proofing of the articles or corrections after their publication to a minimum, the authors submitting to the journals published by the University of Tehran are required, upon submission, to review and approve an automatically-generated presentation of author information, as in a published record, based on their provided information. This includes how author information will appear in databases like PubMed or Scopus. Therefore, the authors should enter their information in the provided submission area in a way that is bibliographically consistent with their previous publications.
Any change in authorship (i.e. order, addition, and deletion of authors) after initial submission must be approved by all authors. Authors should determine and come to an agreement about the order of authorship among themselves. In addition, any alterations must be clarified to the editor. In line with COPE guidelines, University of Tehran requires written confirmation from all authors that they agree with any proposed changes in authorship of submission(s) or published item(s). This confirmation must be via direct email from each author. It is the corresponding author’s responsibility to ensure that all authors confirm they agree with the proposed changes. If there is disagreement amongst the authors concerning authorship and a satisfactory agreement cannot be reached, the authors must contact their institution(s) for a resolution. It is not the journal editor’s responsibility to resolve authorship disputes. A change in authorship of a published article can only be amended via publication of an Erratum.
ORCID (Open Researcher and Contributor ID) is an open, non-profit, community-based effort to provide a registry of unique researcher identifiers and a transparent method of linking research activities and outputs to these identifiers. University of Tehran encourages use of these unique identifiers to identify the individuals who submit a work to the journals or those who are selected as reviewers to undertake the peer-review of submissions for the journals. The editorial team members of the journals also include their unique identifiers in their profiles.
Research articles and non-research articles (e.g. Opinion, Review, and Commentary articles) must cite appropriate and relevant literature in support of the claims made. Excessive and inappropriate self-citation or coordinated efforts among several authors to collectively self-cite is strongly discouraged.
Authors should consider the following guidelines when preparing their manuscript:
- Any statement in the manuscript that relies on external sources of information (i.e. not the authors' own new ideas or findings or general knowledge) should use a citation.
- Authors should avoid citing derivations of original work. For example, they should cite the original work rather than a review article that cites an original work.
- Authors should ensure that their citations are accurate (i.e. they should ensure the citation supports the statement made in their manuscript and should not misrepresent another work by citing it if it does not support the point the authors wish to make).
- Authors should not cite sources that they have not read.
- Authors should not preferentially cite their own or their friends’, peers’, or institution’s publications.
- Authors should avoid citing work solely from one country.
- Authors should not use an excessive number of citations to support one point.
- Ideally, authors should cite sources that have undergone peer review where possible.
- Authors should not cite advertisements or advertorial material.
Any manuscript that is submitted to a journal published by University of Tehran must be original and the manuscript or substantial parts of it, must not be under consideration by any other journal. In any case where there is the potential for overlap or duplication we require authors to be transparent. Authors should declare any potentially overlapping publications on submission and where possible, upload these as additional files with the manuscript. Any overlapping publications should be cited. Any ‘in press’ or unpublished manuscript cited or relevant to the Editor’s and reviewers' assessment of the manuscript, should be made available if requested by the Editor. University of Tehran reserves the right to judge potentially overlapping or redundant publications on a case-by-case basis.
In general, the submitted manuscript should not already have been formally published in any journal or in any other citable form. If justified and made clear upon submission, there are exceptions to this rule, such as publication in the form of a poster or conference presentation.
University of Tehran follows the policies of the ICMJE in relation to overlapping publications.
Pre-print servers and author/institutional repositories
The journals published by University of Tehran will consider peer reviewing manuscripts that have been posted on an author's personal or institutional website. Material that has formed part of an academic thesis and been placed in the public domain, as required by the awarding institution, will also be considered by journals published by University of Tehran.
Summary clinical trial results in public registries
Posting of summary clinical trial results in publicly accessible databases is generally not considered duplicate publication. University of Tehran requires authors of manuscripts reporting clinical trials to have registered their trial in a suitably accessible registry
Authors should be aware that replication of text from their own previous publications is text recycling (also referred to as self-plagiarism) and in some cases is considered unacceptable. Where overlap of text with authors’ own previous publications is necessary or unavoidable, duplication must always be reported transparently and be properly attributed and be compliant with copyright requirements. If a submission contains text that has been published elsewhere, authors should notify the journal editors in the submission cover letter.
All research articles, and most other article types, published by the journals of University of Tehran undergo a thorough peer review process. This usually involves review by two independent peer reviewers. Individual journals may differ in their peer review processes. For an individual journal’s peer review policy, please see the journal website.
Peer review policy
All submissions to journals published by University of Tehran are assessed by an editor, who will decide whether they are suitable for peer review. Where an editor is on the author list or has any other competing interest regarding a specific submission, another member of the editorial board will be assigned to assume responsibility for overseeing peer review. Submissions felt to be suitable for consideration will be sent for peer review by appropriate independent experts. Editors will make a decision based on the reviewers’ reports and authors are sent these reports along with the editorial decision on their manuscript. Authors should note that even in light of one positive report, concerns raised by another reviewer may fundamentally undermine the study and result in the manuscript being rejected.
All journals published by University of Tehran operate a closed double-blind peer review process. The authors and the reviewers will be treated anonymously.
Authors may suggest potential reviewers if they wish; however, decision to consider these reviewers is at the editor's discretion. Authors should not suggest recent collaborators or colleagues who work in the same institution as themselves. Authors who wish to suggest peer reviewers can do so in the cover letter and should provide institutional email addresses where possible or information which will help the Editor to verify and identity the potential introduced reviewer (for example an ORCID or Scopus ID).
Authors may request exclusion of individuals as peer reviewers, but they should explain the reasons in their cover letter on submission. Authors should not exclude too many individuals as this may hinder the peer review process. Please note that the editor may choose to invite excluded peer reviewers.
Intentionally falsifying information, for example, suggesting reviewers with a false name or email address, will result in rejection of the manuscript and may lead to further investigation in line with our misconduct policy.
Editors will treat all submission to their journal in confidence. Reviewers are also required to treat manuscripts confidentially. Journals published by University of Tehran will not share manuscripts with third parties, except in cases of suspected misconduct.
University of Tehran takes seriously all allegations of potential misconduct. The journals published by University of Tehran follow the COPE guidelines to deal with cases of suspected misconduct.
In cases of suspected research or publication misconduct, it may be necessary for the editor to contact and share manuscripts with third parties, for example, author(s)’ institution(s) and ethics committee(s). University of Tehran may also seek advice from COPE and discuss anonymized cases in the COPE Forum.
All research involving humans (including human data and human material) and animals must have been carried out within an appropriate ethical framework. If there is suspicion that research has not taken place within an appropriate ethical framework, the editor may reject a manuscript and may inform third parties, for example, author(s)’ institution(s) and ethics committee(s).
In cases of proven research misconduct involving published articles, or where the scientific integrity of the article is significantly undermined, articles may be retracted.
All journals published by University of Tehran will follow the COPE guidelines to deal with cases of potential publication misconduct.
- All digital images in manuscripts considered for publication will be scrutinized for any indication of manipulation that is inconsistent with the following guidelines. Manipulation that violates these guidelines may result in delays in manuscript processing or rejection, or retraction of a published article.
- No specific feature within an image may be enhanced, obscured, moved, removed, or introduced.
- The grouping of images from different parts of the same gel or from different gels, fields or exposures must be made explicit by the arrangement of the figure (i.e. using dividing lines) and in the text of the figure legend.
- Adjustments of brightness, contrast, or color balance are acceptable if they are applied to every pixel in the image and as long as they do not obscure, eliminate or misrepresent any information present in the original, including the background. Non-linear adjustments (e.g. changes to gamma settings) must be disclosed in the figure legend.
Any questions raised during or after the peer review process will be referred to the editor, who will request the original data from the author(s) for comparison with the prepared figures. If the original data cannot be produced, the submission may be rejected or in the case of a published article, retracted. Any case in which the manipulation affects the interpretation of the data will result in rejection or retraction. Cases of suspected misconduct will be reported to the author(s)’ institution(s).
All articles in the journal are reviewed before publication. If plagiarism is identified, we will follow COPE guidelines.
Plagiarism includes, but is not limited to:
* Directly copying text from other sources
* Copying ideas, images, or data from other sources
* Reusing text from your own previous publications
* Using an idea from another source with slightly modified language
If plagiarism is detected during the peer review process, the submission may be rejected. If plagiarism is detected after publication, we reserve the right to issue a correction or retract the paper, as appropriate. We reserve the right to inform authors' institutions about plagiarism detected either before or after publication.
Corrections and retractions
Rarely, it may be necessary for University of Tehran to publish corrections to or retractions of articles published in its journals to maintain the integrity of the academic record.
In line with accepted norms of the academic community, corrections to, or retractions of published articles will be made by publishing an Erratum or a Retraction article, without altering the original article in any way other than to add a prominent link to the Erratum/Retraction article. The original article remains in the public domain and the subsequent Erratum or Retraction will be widely indexed. In the exceptional event that material is considered to infringe certain rights or is defamatory, we may have to remove that material from our site and archive sites.
It may be possible for minor corrections to published articles to be made by the original author(s) posting a comment on the published article. This would only be appropriate where the changes do not affect the results or conclusions of the article.
Changes to published articles that affect the interpretation and conclusion of the article, but do not fully invalidate the article, will, at the editor(s)’ discretion, be corrected via publication of an Erratum that is indexed and linked to the original article. Changes in authorship of published articles are corrected via an Erratum.
On rare occasions, when the scientific information in an article is substantially undermined, it may be necessary for published articles to be retracted. University of Tehran will follow the COPE guidelines in such cases. Retracted articles are indexed and linked to the original article.
