2.  Disclosure of Conflicts of Interest

A conflict of interest occurs when an individual's objectivity is potentially compromised by a desire for financial gain, prominence, professional advancement or a successful outcome. JCMA Editors strive to ensure that what is published in the Journal is as balanced, objective and evidence-based as possible. Since it can be difficult to distinguish between an actual conflict of interest and a perceived conflict of interest, the Journal requires authors to disclose all and any potential conflicts of interest.

Conflicts of interest may be financial or non-financial. Financial conflicts include financial relationships such as honoraria; educational grants; participation in speakers' bureaus; membership, employment, consultancies, stock ownership, or other equity interest; expert testimony or patent-licensing arrangements. Non-financial conflicts include personal or professional relationships, affiliations, academic competition, intellectual passion, knowledge or beliefs that might affect objectivity.

3.  Ethical Approval of Studies and Informed Consent

For human or animal experimental investigations, appropriate institutional review board or ethics committee approval is required, and such approval should be stated in the methods section of the manuscript. For those investigators who do not have formal ethics review committees, the principles outlined in the Declaration of Helsinki should be followed (World Medical Association. Declaration of Helsinki: ethical principles for medical research involving human subjects. Available at:

For investigation of human subjects, state explicitly in the methods section of the manuscript that informed consent was obtained from all participating adult subjects and from parents or legal guardians for minors or incapacitated adults, together with the manner in which informed written consent was obtained.

For work involving animals, the guidelines  for  their  care and use that were followed should be stated in the methods section of the manuscript. For those investigators who do not have formal institutional guidelines relating to animal experiments, the European Commission Directive 86/609/EEC for ani- mal experiments (available at chemicals/lab_animals/legislation_en.htm) should be followed and the same should be stated in the methods section of the manuscript.

4.  Reporting Clinical Trials

All randomized controlled trials submitted for publication should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart (please go to http://www.consort- for more information). The JCMA has adopted the ICMJE proposal that requires, as a condition of consideration for publication of clinical trials, registration in a public trials registry. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration. Further information can be found at http://

5.  Identification of Patients in Descriptions, Photographs and Pedigrees

Please state informed written consent was obtained in the manuscript if your manuscript contains patient descriptions, photographs and pedigrees. Omitting data or making data less specific to de-identify patients is acceptable, but changing any such data is not acceptable. State explicitly in the methods section of the manuscript that informed consent was obtained from all participating adult subjects or from parents or legal guardians for minors or incapacitated adults, together with the manner in  which written informed consent was obtained.

6.  Previous Publication or Duplicate Submission

Submitted manuscripts are considered with the understanding that they have not been published previously in print or electronic format (except in abstract or poster form) and are not under consideration in totality or in part by another publication or electronic medium.

7.  Basic Criteria

Articles should be written in English, using American English spelling, and meet the following basic criteria: the material is original, the information is important, the writing is clear and concise, the study methods are appropriate, the data are valid, and the conclusions are reasonable and supported by the data.

8.  Language (usage and editing services)

Please write your text in good English (American or British usage is accepted, but not a mixture of these). Authors who feel their English language manuscript may require editing to eliminate possible grammatical or spelling errors and to conform to correct scientific English may wish to use the English Language Editing service available from Wolters Kluwer Author Services*. For manuscripts that are judged by JCMA Editors or reviewers to be written in poor English but otherwise worthy of consideration for publication, authors are required to attach the English Editing Certificate. Otherwise, their manuscript will be rejected.

Abstracts for Case Reports should be unstructured (in one single paragraph with no section headings), no more than 200 words long, and include the significance and purpose of the case presentation, the diagnostic methods of the case, the key data, and brief comments and suggestions with regard to the case.

Abstracts for Review Articles (not more than 300 words) and Brief Communications (not more than 200 words) should also be unstructured (in one single paragraph with no section headings).

Keywords should be taken from the Medical Subject Headings (MeSH) list of Index Medicus (http://www.nlm.nih. gov/mesh/meshhome.html).

No abstract or keywords are required for Editorials and Letters to the Editor.

10.3.  Main Text

No author information such as names, affiliations and contact information should appear in the main text. The text for Original Articles and Brief Communications should be organized into the following sections: Introduction, Methods, Results, Discussion, Conflicts of Interest Statement (if any), Acknowledgments (if any), and References. Subheadings in long papers are acceptable if needed for clarification and ease of reading. Sections for Case Reports are: Introduction, Case Report, Discussion, Conflicts of Interest Statement (if any), Acknowledgments (if any), and References. Each section should begin on a new page.

10.3.1.    Abbreviations

Where a term/definition will be continually referred to, it must be written in full when it first appears in the text, followed by the subsequent abbreviation in parentheses. Thereafter, the abbreviation may be used. An abbreviation should not be first defined in any section heading; if an abbreviation has previously been defined in the text, then the abbreviation may be used in a subsequent section heading. Restrict the number of abbreviations to those that are absolutely necessary.

10.3.2.    Numbers

Numbers that begin a sentence or those that are less than 10 should be spelled out using letters. Centuries and decades should be spelled out, e.g., the Eighties or nineteenth century. Laboratory parameters, time, temperature, length, area, mass, and volume should be expressed using digits.

10.3.3.  Units

Système International (SI) units must be used, with the exception of blood pressure values which are to be reported in mmHg. Use the metric system for the expression of length, area, mass, and volume. Temperatures are to be given in degrees Celsius.

10.3.4.    Names of drugs, devices and other products

Use the Recommended International Non-proprietary  Name (rINN) for medicinal substances, unless the specific trade name of a drug is directly relevant to the discussion. Generic drug names should appear in lowercase letters in the text. If a specific proprietary drug needs to be identified, the brand name may appear only once in the manuscript in parentheses following the generic name the first time the drug is mentioned in the text.

For devices and other products, the specific brand or trade name, the manufacturer and their location (city, state, country) should be provided the first time the device or product is mentioned in the text, for example, quot;…SPSS version 11 was used (SPSS Inc., Chicago, IL, USA)". Thereafter, the generic term (if appropriate) should be used.

10.3.5.  Gene nomenclature

Current standard international nomenclature for genes should be adhered to. For human genes, use genetic notation and symbols approved by the HUGO Gene Nomenclature Committee (http:// You may also refer to the resources available on PubMed at The Human Genome Variation Society has a useful site that provides guidance in naming mutations at index.html. In your manuscript, genes should be typed in italic font and include the accession number.

10.3.6.    Statistical requirements

Statistical analysis is essential for all research papers except Case Reports. Use correct nomenclature for statistical methods (e.g., two sample t test, not unpaired t test). Descriptive statistics should follow the scales used in data description. Inferential statistics are important for interpreting results and should be described in detail.

All p values should be presented to the third decimal place for accuracy. The smallest value that should be  expressed is p <

0.001 since additional zeros do not convey useful information; the largest p value that should be expressed is p > 0.99.

      1. Personal communications and unpublished data

        These sources cannot be included in the references list but may be described in the text. The author(s) must give the full name and highest academic degree of the person, the date of the com- munication, and indicate whether it was in oral or written (letter, fax, e-mail) form. A signed statement of permission should be included from each person identified as a source of information in a personal communication or as a source for unpublished data.

10.4.  Conflicts of Interest Statement and/or Funding/ Support Statement

Since it is difficult to distinguish between an actual conflict of interest and a perceived conflict of interest, the JCMA requires authors to disclose all and any potential conflicts of interest and let readers judge for themselves. Therefore, please ensure that you provide information about any potential financial and non-financial conflicts of interest (see Section 2 for more information) in a concise paragraph after the main text.

All financial and material support for the research, work, writing and editorial assistance from internal or external agencies, including commercial companies, should be clearly and completely identified in a Funding/Support Statement.

10.5.  Acknowledgments

After the Conflicts of Interest Statement and/or Funding/ Support Statement, general acknowledgments for consultations and statistical analyses should be listed concisely, including the names of the individuals who were directly involved. Consent should be obtained from those individuals before their names are listed in this section. Those acknowledged should not include secretarial, clerical or technical staff whose participation was limited to the performance of their normal duties.

10.6.  References

10.7.     Tables

Tables should supplement, not duplicate, the text. They should have a concise table heading, be self-explanatory, and numbered consecutively in the order of their citation in the text. Items requiring explanatory footnotes should be denoted using superscripted lowercase letters (a, b, c, etc.), with the footnotes arranged under the table in alphabetical order. Asterisks (*, **) are used only to indicate the probability level of tests of significance. Abbreviations used in the table must be defined and placed after the footnotes in alphabetical order. If you include a block of data or table from another source, whether published or unpublished, you must acknowledge the original source.

10.8.     Figures

10.8.1.    General guidelines

The number of figures should be restricted to the minimum necessary to support the textual material. Figures should have an informative figure legend and be numbered in the order of their citation in the text. All symbols and abbreviations should be defined in the figure legend in alphabetical order. Items requiring explanatory footnotes should follow the same style as that for tables as described in Section 10.7.

Patient identification should be obscured. All lettering should be done professionally and should be in proportion to the drawing, graph or photograph. Photomicrographs must include an internal scale marker, and the legend should state the type of specimen, original magnification and stain.

Figures must be submitted as separate picture files, at the correct resolution (see Section 10.8.2.) and named according to the figure number and format, e.g., "Fig1.tif", "Fig2.jpg".

10.8.2.  Formats

Tables. Photographs of tables are not acceptable. Type each table, 1.5 spacing throughout (including column headings, footnotes, and data), on a separate page. Tables may be included as part of the Main Body file and placed after the References section. Number the tables in sequence in Arabic numerals and supply a concise, informative title for each one. Each column in the tables should carry a concise heading describing the data in the column. Use lowercase superscript letters to designate footnotes, and type the footnotes below the tables to which they refer. Tables are cited in the text in numerical order. Each table should be able to be understood without consulting the text.

Like text, tables should be prepared using a standard word-processing program and may be included within the main body text document, or uploaded separately. Do not upload table files more than once (that is, in the main document and in separate files). Acceptable document file types for tables include .DOC and .DOCX; do not submit PDF, XLS or XLSX type files.

Acceptable figure file formats

  • Do not embed figures into the main body file
  • All final digital figures for accepted manuscripts must be submitted in EPS, TIFF, JPG.
  • Each figure must be uploaded as a separate file.
  • Histology figures must be in color.
  • Monochrome images (such as line graphs) should be prepared at a resolution of 1200 DPI.
  • Halftones images (black/white or color) should be prepared at a resolution of 300 DPI.
  • Combination halftones (images containing both pictures and text labeling) should be prepared at 600 DPI.
  • Color images must be saved as ''CMYK''. Images saved as ''RGB'' are not acceptable for printing.
  • Your manuscript may be returned to you for correction if the images are of insufficient quality.
  • Artwork submitted to the Journal will be checked for quality. Authors submitting a revised paper will have the opportunity to check the quality of their images and make the necessary changes. This step is required for all revisions.

11.  The Editorial and Peer Review Process

As a general rule, the receipt of a manuscript will be acknowledged within 2 weeks of submission, and authors will be provided with a manuscript reference number for future correspondence. If such an acknowledgment is not received in a reasonable period of time, the author should contact the Editorial Office.

Submissions are reviewed by the Editorial Office to ensure that it contains all parts. Submissions will be rejected if the author has not supplied all the material and documents as outlined in these author instructions.

Manuscripts are then forwarded to the Editor-in-Chief, who makes an initial assessment of it. If the manuscript does not appear to be of sufficient merit or is not appropriate for the Journal, then the manuscript will be rejected promptly without review.

Manuscripts that appear meritorious and appropriate for the Journal are reviewed by at least two Editorial Board members or expert consultants assigned by the Editor-in-Chief. The JCMA follows a double-blind peer review process. Authors may submit a list in their cover letter of reviewers who they wish to review or not to review their manuscript. However, the actual peer reviewers invited will remain anonymous and may or may not be the reviewers suggested by the authors as the selection of reviewers is at the sole discretion of JCMA Editors. The editors and reviewers will not disclose any information about a manuscript or its review to anyone except the manuscript's corresponding author.

The corresponding author will usually be notified within 6 weeks of whether the submitted article is accepted for publication, rejected, or subject to revision before acceptance (however, do note that delays are sometimes unavoidable). If revisions are required, authors are asked to return a revised manuscript to the Editorial Office within 60 days (via the same method by which the manuscript was originally submitted). Please notify the Editorial Office in advance if additional time is needed or if you choose not to submit a revised manuscript.

Manuscripts received from Editorial Board members will be screened by the Editor in Chief and sent to external peer reviewers. The editorial board members who are authors will be excluded from publication decisions.

12.  Preparation for Publication

Once a manuscript has been accepted for publication, authors should submit the final version of their manuscript in MS Word format, with all tables/figures as applicable, via the same method by which the manuscript was originally submitted via EM. It is a basic requirement that the manuscript be prepared using good English. The Editorial Office reserves the right to edit poor English as suggested by the reviewer(s) and/or Editorial Board before the final version is decided.

Accepted manuscripts are then presented to the Publisher to be copyedited according to the Journal's style and the galley proofs in the form of a PDF file are sent by the Publisher to the corresponding author for final approval. Authors are responsible for all statements made in their work, including changes made by the copy editor.

Proofreading is solely the authors' responsibility. Note that the Editorial Board reserves the right to make revisions to the manuscript and the Publisher may proceed with the publication of your article if no response from the author(s) is received.

13.  Publication Charges and Reprints

Starting from 1 January 2021, authors of accepted articles will be charged a publication fee of US$800(NT$24000) for all articles (except for invited articles and editorials). The Journal will bear the cost of publication for articles of 8 printed pages or less for Original Articles. Authors will be charged US$100 (NT$3000) per extra page. Authors will also be charged a flat fee of US$300 (NT$9000) per article if it contains any figures and/or tables in color for print.  

Professional reprints (which include a cover page) of your article may be ordered at prices based on the cost of production.​
