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), are exempt.
Registries include: (1) the registry sponsored by the United States National Library of Medicine (; (2) ISRCTN Resistry (; (3) the Australian New Zealand Clinical Trials Registry (; (4) the Chinese Clinical Trials Registry (; (5) the Clinical Trials Registry-India (; (6) University hospital Medical Information Network (UMIN) (; and (7) the Clinical Research Information Service-South Korea (

5.1. Original Articles
General Principles
1) Manuscripts should be prepared using MicroSoft Word(.doc). All portions of the manuscript - including the title page, abstract, main text, acknowledgments, references, individual tables, and figure legends - should be double spaced with the font size of 12 with 3-cm blank margin in both sides, top and bottom of A4-sized paper (21×30 cm) or North American letter-sized paper (81?2 in×11 in). The numbers on each page of the manuscript should be placed at the center of the bottom in a sequential manner starting from the title page.
2) Acronyms should only be used when absolutely necessary for clarity. In cases in which the use of acronyms is desirable due to the repetition, the acronym should be expressed in a parenthesis when the corresponding terminology first appears in the manuscript.
3) Laboratory measurements should be used in SI units (International System of Units). However, in some cases, non-SI units (Conventional Units) can also be used in a versatile manner. But the usage of units should be consistent.
4) The manuscript should be arranged in the following order: Title page, Abstract and Keywords, Main text (Introduction, Methods, Results, Discussion), Acknowledgments, References, Tables and Figures.

Title page and Abstract
1) The title page should be as follows; the title of the manuscript, a short running title less than 50 characters, names of all authors and their current affiliations. In cases in which the authors belong to multiple affiliations, the affiliations during the study being reported should be matched to the authors’ names using a superscript of Arabic numerals.
2) The title of the manuscript should be no longer than 20 English words. The first letter of each word of the title must be capitalized. Acronyms should not be used in title except for special situations.
3) The name, mailing address, and e-mail address of the corresponding author should be displayed at the bottom of the title page.
4) Provide the word count for the text only, excluding abstract, acknowledgments, figure legends, and references.
5) The number of figures and tables should be provided in the title page.
6) The abstract must not exceed 250 words.
7) The abstract must be structured into Background, Methods, Results and Conclusion.
8) The abstract must be self-contained and clear without reference to the text.
9) Three to ten keywords, reflecting the manuscript contents, must be provided at the end of the Abstract in MeSH terms of the Index Medicus (

Main text
1) The main text should be structured as Introduction, Methods, Results and Discussion. Use headings and subheadings in the Methods section and Results section. Every reference, figure and table must be cited numerically in the order mentioned in the text.
2) Methods: Materials, methods, and study design should be presented in detail. In experimental research, methods should be described in such a manner that the experiments can be reproduced by the readers. A statement concerning IRB approval and consent procedures must appear at the beginning of the Methods section.
3) Results: A detailed description of the study results should be clearly arranged in a logical manner. In cases in which tables are used, the contents described in tables should not be redundantly described in the main text, but the important trends and points should be emphasized.
4) Discussion: New and important observations should be emphasized. A redundant description of the results is not acceptable. The significance and limitation of the observed findings should be described. There should be a link between the conclusions and the goals of the study. Conclusions not adequately supported by the data must be avoided.
