1) In regard to the process of reviewing and assessing the
manuscripts, including the ethical guidelines and plagiarism/duplicate
publication and study misconduct, it
should conform to the ethical guidelines specified in the
Recommendations for the Conduct, Reporting, Editing,
and Publication of Scholarly Work in Medical Journals
), which were
established by the International Committee of Medical
Journal Editors (ICMJE). For the policies on the research
and publication ethics not stated in this instruction, Good
Publication Practice Guidelines for Medical Journals 2nd
(Korean Association of Medical Journal Editors, KAMJE; http://kamje.or.kr/intro.php?body=publishing_ethics
or Guidelines on Good Publication (Committee on
Publication Ethics, COPE; http://publicationethics.org/resources/guidelines
) can be applied.
2) Disclosure of conflicts of interest
Financial sponsorship should be stated in the conflicts of
interest. Any other financial support associated with the
study, including stocks or consultation arrangements with
pharmaceutical companies should be stated at the end of
the text, under a subheading “Conflicts of interest.”
3) Statement of informed consent
Human study must conform to ethical standards, and be
approved by the appropriate Institutional Review Board
(IRB). A statement concerning IRB approval and consent
procedures must appear at the beginning of the “Methods”
section. Any systematic data gathering effort in patients
or volunteers must be approved by an IRB or adhere
to appropriate local/national regulations. Authors may
be questioned about the details of consent forms or the
consent process. On occasion, the Editor-in-Chief may
request a copy of the approved IRB application from the
4) Statement of human and animal right
Clinical research studies must state that the work was
done in accordance with the Ethical Principles for Medical
Research Involving Human Subjects
outlined in the
Declaration of Helsinki in 1975 (revised in 2013; http://www.wma.net/en/30publications/10policies/b3/index.html
). Clinical studies that do not meet the Declaration of
Helsinki will not be considered for publication. Human
subjects must not be identifiable. Patients’ name, initial,
hospital number, date of birth, or other protected healthcare
information must not be disclosed. Animal research
studies must state that the work was performed according
to National or Institutional Guide for the Care and Use
of Laboratory Animals, and the ethical treatment of all
experimental animals must be observed.
According to the guidelines of the ICMJE, authorship
credit must be based on 1) substantial contributions to
the concept and design, or acquisition of data, or analysis
and interpretation of data; 2) drafting the article or revising
it critically for important intellectual content; 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.
All authors must meet the above four conditions.
For original article, all authors are required to describe
author’s specific contributions that will be published in
the Author contributions section.
6) Originality and duplicate publication
All submitted manuscripts should be original and should
not be considered by other scientific journals for publication
at the same time. No part of the accepted paper
should be duplicated in another scientific journal without
permission by Editorial Board. If duplicate publications
related to the papers of this journal are detected, sanctions
against authors range from requesting their institutions to
assess the facts, requesting a Letter to the Editor-in-Chief
acknowledging the error and voluntarily withdrawing a
paper, to a ban on publication in EnM
up to 3 years.
7) Clinical trials registry
We strongly recommend, as a condition of consideration
for publication, registration in a public trials registry.
Trials must register at or before the onset of patient enrollment.
This policy applies to any clinical trial starting
enrollment after January 1, 2006. For trials that began enrollment
before this date, we request registration by April
1, 2006, before considering the trial for publication. We
define a clinical trial as any research project that prospectively
assigns human subjects to intervention or comparison
groups to study the cause-and-effect relationship
between a medical intervention and a health outcome.
Studies designed for other purposes, such as studies on
pharmacokinetics or major toxicity (e.g., phase 1 trials),
Registries include: 1) the registry sponsored by the
United States National Library of Medicine (www.clinicaltrials.gov
2) ISRCTN Resistry (http://www.isrctn.com/
); 3) Australian New Zealand Clinical Trials Registry
); 4) Chinese Clinical Trials
); 5) the Clinical Trials
); 6) University hospital
Medical Information Network (UMIN) (http://www.umin.ac.jp/ctr
); and 7) the Clinical Research Information
Service-Republic of Korea (CRiS) (https://cris.nih.go.kr/cris/
). Reporting of randomized controlled trials should
follow the guidelines of The CONSORT Statement (http://www.consort-statement.org
