Publication ethics and plagiarism policy
The journal follows the guidelines of the Committee on Publication Ethics (COPE) with regard to matters of publication ethics such as cases of plagiarism and duplicate publication. Authors may not submit the same manuscript to more than one journal concurrently.
Human subjects and patient consent
Medical research involving human subjects must be conducted according to the World Medical Association Declaration of Helsinki. The research protocol must be approved by the locally appointed ethics committee. The informed consent of patients or volunteers (or their guardian), in particular when there is identifying information, must be obtained. These facts must be indicated in the manuscript.
The journal aims for detailed and high quality reporting of animal experiments and suggests authors follow the ARRIVE guidelines when preparing their manuscript. Authors may be required to provide evidence that they obtained ethical and /or legal approval prior to conducting the research.
Registration of clinical trials
All clinical trials, in particular those involving pharmaceuticals, devices, or aspects relating to nutrition, should be registered prospectively in publically accessible databases (such as www.clinicaltrials.gov and www.clinicaltrialsregister.eu) and the paper should include registration numbers and the name of the register. Clinical trials must be reported according to CONSORT guidelines.
Conflict of interest
All authors must make a formal statement at the time of submission indicating any potential conflict of interest that might constitute an embarrassment to any of the authors if it were not to be declared and were to emerge after publication. Such conflicts might include, but are not limited to, shareholding in or receipt of a grant or consultancy fee from a company whose product features in the submitted manuscript or which manufactures a competing product.
International Committee of Medical Journal Editors and an ICMJE disclosure of potential conflicts of interest (COI) form must be submitted for each author at the time of manuscript submission. Forms must be submitted even if there is no conflict of interest. It is the responsibility of the corresponding author to ensure that all authors adhere to this policy prior to submission.
A conflict of interest statement must also be included in the manuscript after any "Acknowledgements" and "Funding" sections and should summarize all aspects of any conflicts of interest included on the ICMJE form. If there is no conflict of interest, authors must include 'Conflict of Interest: none declared' in their manuscript.
