Guide for Authors

1. Manuscript Submission

Manuscripts for Kidney Research and Clinical Practice should be submitted online at For editorial questions, please contact us via e-mail (, telephone (+82 2 3486-8736), or fax (+82 2 3486-8737).

Important information

Articles should be prepared in the simplest form possible and submitted in Microsoft Word (*.doc or *.docx). Manuscripts must be typed in English and double-spaced. All pages must be numbered consecutively starting from the title page. You may use automatic page numbering, but do NOT use other kinds of automatic formatting such as footnotes. Place text, references, figures, tables and legends in one file with each figure or table on a new page.

Please ensure that the following submission documents are also included, where applicable:
(1) A cover letter. It must include your name, address, telephone and fax numbers, e-mail address, and state that all authors have contributed to the paper and have never submitted the manuscript, in whole or in part, to other journals.
(2) A conflict of interest disclosure statement (see relevant section below).
(3) Articles covering the use of human samples in research and human experiments must be approved by the relevant review committee (see relevant section below).
(4) Articles covering the use of animals in experiments must be approved by the relevant authorities.
(5) Articles where human subjects can be identified in descriptions, photographs or pedigrees must be accompanied by a signed statement of informed consent to publish (in print and online) the descriptions, photographs and pedigrees from each subject who can be identified (see relevant section below).
(6) Clinical trials are recommended to be registered at a primary national clinical trial registration site such as,, or other sites accredited by the World Health Organization or the International Committee of Medical Journal Editors.
(7) Where material has been reproduced from other copyrighted sources, letter(s) of permission from the copyright holder(s) to use the copyrighted sources must be supplied.
(8) 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, concise and grammatically correct, the study methods are appropriate, the data are valid, and the conclusions are reasonable and supported by the data. For non-native English-speaking authors, we suggest that manuscripts be checked and edited by a native English speaker.

2. Types of Articles

2.1. Review Articles
These describe new developments of significance in the field of nephrology, and highlight unresolved questions and future directions. Most reviews are solicited by the editors, but unsolicited submissions may also be considered for publication. Review articles should include Abstract, Introduction, brief main headings and References. The text should be limited to 5000 words (excluding tables, figures and references).

2.2. Original Articles
These are expected to present major advances and important new research results. Section headings should include Abstract, Introduction, Methods, Results, Discussion, Conflict of Interest, Acknowledgments (if applicable), and References. The text should be limited to 4000 words (excluding tables, figures and references) and 40 references.

2.3. Case Reports
These are short peer-reviewed papers presenting novel findings in clinical studies. Case reports are only published if they illustrate a rare occurrence of important clinical importance. Section headings should include Abstract, Introduction, Case, Discussion, and References. The text should be limited to 1500 words (excluding tables, figures and references) and 15 references. A maximum of 4 figures/tables may be included.

2.4. Letters to the Editor
These are letters about readers' opinions or issues of concern on previously published articles in the journal. Receipt of letters will not be acknowledged nor are authors generally consulted before publication. The text should be limited to 400 words (excluding tables, figures and references) and 5 references. Accepted letters are subject to editing for clarity and space.

2.5. Editorials
These are manuscripts that are related to materials within an issue; they raise challenging questions or explore controversies. The editor solicits such opinion pieces. The order of the submitted manuscript includes title page, integrated discussion, conflict of interest, acknowledgments (if applicable) and references. The text should be limited to 1500 words (excluding references) and 10 references. No figures or tables are included.

2.6. Images in Practice
These present classic images of common medical conditions in clinical nephrology. Images are an important part of much of what we do and learn in clinical practice. The text should be limited to 300 words. There should be no more than two figures. No tables or references are included.

3. Manuscript Preparation

3.1. Title page
The title page should include article title, names (spelled out in full in order of first name, initials of middle name and last name) of all authors, and the institutions with which they are affiliated, short running title not exceeding 50 characters, separate word count for abstract and text, and corresponding author details (name, address, phone, fax and e-mail information). The individual contribution of each co-author must also be detailed.

3.2. Abstract and Keywords
Abstract should not exceed 250 words in original or review articles and 150 words in case reports. It must be written for easy reading with no abbreviations. The abstract of the original article should be divided into four subsections: Background, Methods, Results, and Conclusions. 3–5 keywords should be listed below the abstract. For selecting keywords, refer to the Index Medicus Medical Subject Headings (Available from:

3.3. Main Text
The text for original articles, for example, should include the following sections: Introduction, Methods, Results, and Discussion. The Introduction should be as concise as possible, without subheadings. The Methods section should be sufficiently detailed. Subheadings may be used to organize the Results and Discussion. Each section should begin on a new page.

Where a term/definition is continually referred to (3 times or more in the text), it is written in full when it first appears, followed by the subsequent abbreviation in parentheses (even if it was previously defined in the abstract); thereafter, the abbreviation is used.

Gene nomenclature
Current standard international nomenclature for genes should be adhered to. Genes should be typed in italic font and include the accession number. For human genes, use genetic notation and symbols approved by the HUGO Gene Nomenclature Committee ( or refer to PubMed (

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

3.4. References

Citing references in text
References should be cited with Arabic numerals in square brackets. References are numbered consecutively in order of appearance in text. Multiple references are separated by closed-up commas and ranges are indicated with en dash. References cited in tables or figure legends should be included in sequence at the point where the table or figure is first mentioned in text. Abstracts should not be cited unless it is the only available reference to an important concept. Uncompleted work or work that has not yet been accepted for publication (i.e. unpublished observation, personal communication) should not be cited as references.

When referring to a study, if the reference has only 1 author, then list the author name directly (e.g. Hawkins [1] reported that...); if the reference has 2 authors, both surnames are listed (e.g. Hawkins and Price [1] reported that…); if the reference has 3 authors or more, then list the surname of the first author only followed by "et al" (e.g. Hawkins et al [1] reported that…). Note that "et al" has not end period and is not in italics.

References section
References are limited to those cited in text and listed in numerical order, NOT alphabetical order. They should include, in order, author names, article title, journal name, volume, inclusive page numbers and year. If there is only one page, state if the article is an abstract or letter. Names of all authors should be listed, and should include the last name and initials of the first name and middle name. Journal names should be in italics and abbreviations for journal titles should conform to those used in MEDLINE. If citing a website, author information, article title, website address and the date the site was accessed should be provided. For an article in press, the journal name and, if possible, the volume and year, must be provided.

Note the use of italics, semi-colons, colons, en dashes, word capitalization, and page range.

3.5. Conflicts of Interest
The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors' interpretation of the data. Examples of potential conflicts of interest include financial support from or connections to pharmaceutical companies, political pressure from interest groups, and academically related issues. Conflict of interest statements will be published at the end of the text of the article, before the References section. Please consult the Committee on Publishing Ethics guidelines ( on conflict of interest.

3.6. Acknowledgments
General acknowledgments for consultations, statistical analysis and so on should be listed after main body of text, before the References section, including the names of the individuals involved. All financial and material support for the research and the work should be stated here clearly explicitly.

3.7. Tables
Tables are numbered consecutively using Arabic numerals in the order of their citation in text. Tables should be typed double-spaced on separate pages in as simple a form as possible. Table titles should be short and descriptive (e.g. Table 1. Demographic characteristics of patients). Information requiring extra explanatory footnotes should be denoted using these symbols (in order of appearance): *, †, ‡, §, ∥, #, **, ††, ‡‡. When there are more than 10 footnotes, use superscript lowercase letters. Abbreviations used in the table must be defined and placed after the footnotes as shown here: CT, computed tomography; MRI, magnetic resonance imaging. Certain words can be abbreviated in tables as follows: years to yr, months to mo, days to d, hours to hr, minutes to min, seconds to sec, and to &. Use en dash for empty entries.

3.8. Figures
Figure legends should be submitted for all figures. They should be brief and specific, and placed on a separate sheet after the References section. Figures are numbered consecutively using Arabic numerals in the order of their citation in the text. Figures should be uploaded as separate files, not embedded in the manuscript file. Figures that are line drawing or photographs must be submitted separately in high-resolution EPS or TIFF format (or alternatively in high-resolution JPEG format). Please ensure that files are supplied at the correct resolution (1200 dpi for line drawings and 600 dpi for images such as gels or blots, and 300 dpi for color and half-tone artwork). The files are to be named according to the figure number and format (e.g. Fig1.tif).

Figures that are reproduced from other published sources require written permission from the authors and copyright holders. The first color figure charges $600, and $100 of each additional one. Authors must bear all costs associated with printed color figures. If authors elect not to print in color, in most cases, authors will be able to have their color figures produced in black and white for the printed version of the journals, but the figures will appear in color online.

3.9. Supplemental digital content
Authors can submit supplemental digital content to supplement the information provided in the print version of the manuscript. Supplemental materials will be published online-only. When uploading supplemental files through the online system, please use the "supplemental" file designation. Supplemental materials must be cited consecutively in the main body of the submitted manuscript and include the type of material submitted (e.g., "Suppl. Table 1"; "Suppl. Fig. 1").

4. Copyright
