Please read the complete instructions for authors before submitting
your manuscript to Endocrinology and Metabolism
STUDY CONDUCT AND POLICIES
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
Uniform Requirements for Manuscripts Submitted to
Biomedical Journals: Writing and Editing for Biomedical
Publication (http://www.icmje.org), 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
Association of Medical Journal Editors, KAMJE)” or
“Guidelines on Good Publication (http://publicationethics.
org/resources/guidelines; Committee on Publication
Ethics, COPE)” 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 2000). 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.
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;
and 3) final approval of the version to be published.
All authors must meet the above three conditions.
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 manuscript
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
manuscript, 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) the International Standard Randomized Controlled
Trial Number Registry (http://www.controlledtrials.com); 3) the Australian Clinical Trials Registry
(http://www.actr.org.au); 4) the Chinese Clinical Trials
Register (http://www.chictr.org); 5) the Clinical Trials
Registry-India (http://www.ctri.in); 6) University hospital
Medical Information Network (UMIN) (http://www.umin.ac.jp/ctr); and 7) the Clinical Research Information
Service-Republic of Korea (CRiS) (http://cris.nih.go.kr/
cris/index.jsp). Reporting of randomized controlled trials
should follow the guidelines of The CONSORT Statement
MANUSCRIPT CATEGORIES AND FORMAT

5.2. Review article
A review article is a review focusing on a specific title and
commissioned by the Publication Committee for publishing.
Manuscripts submitted as review articles will be subjected
to the same review process as original research articles.
Instructions for original articles should be followed for review
articles. A review article should include an abstract not
exceeding 200 words, for which the number of references
should not exceed 60.
Editorials are commissioned for the purpose of commenting
on a specific paper published by the journal, not to reflect
the views of the Society. There is no limitation on the format.
But an editorial should be written in no more than 4
pages (A4) with the number of references limited to 20.
5.4. Brief report
Short communications of original research are published as
brief report. The purpose of the category is to permit publication
of very important, high-quality mechanistic studies
that can be concisely presented. These manuscripts should
include a short nonstructured abstract (150 words maximum),
introduction, methods, results, and discussion.
The total manuscript length should not exceed 1,200
words, excluding references and abstract. Brief reports can
include a maximum of 20 references and 2 figures or tables.
5.5. Case report
A case report should be composed of title page, English abstract and keywords, main text (introduction, case report(s),
discussion), conflicts of interest, acknowledgments, references,
tables and figures. The word count of abstract should
be no more than 200 words. The number of keywords is
limited to 3 and the number of references 20. For the other
requirements, follow the same procedure as for original articles.
Images that may help make clinical decisions while being
interesting and educational in terms of the treatment of
endocrinology and metabolism should be prepared with a
manuscript. The manuscript should not be more than 1 page
(A4), with the number of references limited to 5.
5.6. Letters to the editor
A letter should contain constructive criticisms or comments
on a specific paper published by the journal within the previous
6 months. The manuscript should be no more than 1
page (A4), with the number of references limited to 5.
