Publication ethics

Informed consent

All research studies involving human subjects must have received approval of the appropriate institutional ethics committee and informed consent must be obtained from all the patients participating in the studies, prior to manuscript submission.

In cases where the institutional ethics review committee ruled that approval from them was not required or that the need for informed consent was unnecessary, a statement from the committee to this end should be forwarded to the Editor with the manuscript.

Human and animal rights

Studies involving experimental research on animals or humans must conform to the guiding principles of the Declaration of Helsinki. In order to respect a patient`s right to privacy, identifying information such as patients` names, images, initials of hospital numbers should not be included in any published material (tables, figures, text), unless the information is essential for scientific content. In these cases written permission must be obtained from the patient, and should be submitted to the editorial office at the time of manuscript submission. In the case of animal experiments, both national and the institutional guidelines pertaining to the experimental use of laboratory animals should be rigidly followed.

Conflict of interest

The manuscript should contain a statement fully disclosing any conflict of interest related to the manuscript. If there are no conflicts of interest, this should be stated as “none declared”. Material and financial support should also be acknowledged.

Scientific misconduct

Scientific misconduct includes data fabrication, falsification, plagiarism, redundant publication, ghost authorship or other fraudulent research practices. In order to prevent plagiarism issues, all manuscripts sent to the journal will be screened using anti-plagiarism soft-ware. Where there is a suspicion of scientific misconduct, the Editor will act in conformity with the principles stated in the COPE guidelines and if the fraudulent practice is confirmed the manuscript will be rejected outright and without the Editor entering into any further correspondence.

Clinical trials

In case of manuscripts presenting clinical trials, the clinical trial should be registered in a public trials registry at or before the time of first patient enrollment, as a condition for consideration for publication. Trials should be preferably registered in, but any registry that is a primary register of the WHO International Clinical Trials Registry Platform (ICTRP) is acceptable, in accordance with the guidelines of the International Committee of Medical Journal Editors.

Data sharing policy

Authors are encouraged to cite any data referenced in their paper. Whether this has been created by the author or someone else, cited data sets should be included in the reference list. Finally, authors will be encouraged to include a data availability statement.

Intellectual property rights

JCCM is an Open Access journal and aims to publish the most complete and reliable source of information on the discoveries and current developments in the mode of original articles, review articles, case reports, short communications, etc. in all areas of the field and making them freely available through online without any restrictions or any other subscriptions to researchers worldwide.

Sharing and archiving of articles

Authors can archive pre-print and post-print or publisher’s version/PDF on their personal websites, their institution’s repositories, or any non-commercial repository for personal use, internal institutional use, or for permitted scholarly posting. However, it is a recommendation of the editorial team to use the final, published version of the paper with the acknowledgment of the original source of publication and a link should be inserted to the published article on the journal’s website.

Post-publication discussions and corrections

JCCM encourages debate post-publication by submitting a letter to the editor. Post-publication corrections will be published alongside the original article. Corrected manuscripts will be published alongside the original manuscript, so readers can always find the most up-to-date version. All versions will be permanently available and linked to the same DOI. JCCM will be guided by the COPE guidelines when handling corrections, revisions or retraction of articles after publication.
