Reporting guidelines for specific study designs:
For the specific study design, such as randomized control studies, studies of diagnostic accuracy, meta-analyses, observational studies and non-randomized studies, it is recommended that the authors follow the reporting guidelines listed in the following table [1].
ORIGINAL ARTICLES
Original articles are reports of basic or clinical investigations. Although there is no limitation on the length of these manuscripts, the Editorial Board may abridge excessive illustrations and large tables. The manuscript for an original article should be organized in the following sequence: title page, abstract and keywords, introduction, methods, results, discussion, acknowledgments, references, tables, and figure legends.
The cover letter should inform the editor that neither the submitted material nor portions thereof have been published previously or are under consideration for publication elsewhere. It should state any potential conflict of interest that could influence the authors interpretation of the data, such as financial support from or connections to pharmaceutical companies, political pressure from interest groups, or academically related issues.
Title page:
The title page should list the title of the article and the full names and institutional affiliations of all authors. The title should be short, informative, and contain the major key words (no more than 120 characters, not including spaces between words). The use of acronyms and abbreviations should be avoided, and the species of any experimental animal must be indicated in the title. A short running title must also be provided, consisting of fewer than 40 characters including spaces. For a multicenter study, indicate each individual¡¯s affiliation using a superscript Arabic number. Contact information for correspondence must be provided, consisting of the name, academic degree(s), address (institutional affiliation, city, zip code, and country), telephone and fax numbers, and e-mail address.
Abstract and Keywords:
The abstract of the original article should be no more than 250 words and be divided into four subsections: Background/Aims, Methods, Results, and Conclusions. Abbreviations, if needed, should be kept to an absolute minimum and identified clearly. Up to five keywords should be listed below the abstract. For selecting keywords, refer to the Index Medicus Medical Subject Headings [7].
Introduction:
The introduction should include a brief background of the topic for general readers and should refer to the most pertinent papers and relevant findings of others in the field. The specific questions to be addressed by the study should also be described.
Methods:
Methods should be described concisely, but in sufficient detail to allow other qualified investigators to repeat the experiments. The sources of special chemicals or reagents should be given along with the source location (name of company, city, state/province, and country). If needed, include information on the institutional review board/ethics committee approval or waiver and informed consent. Methods of statistical analysis and criteria for statistical significance should be described.
Results:
The results should be presented in logical order using text, tables, and illustrations. Duplication of table or figure content should be avoided.
Discussion:
The discussion section is a concise interpretation and discussion of the data and results. Speculation is permitted, but it must be supported by the presented data. Content already presented in the results should not be repeated in the discussion.
Acknowledgments:
All persons who have made substantial contributions, but who have not met the criteria for authorship, are acknowledged here. All sources of funding applicable to the study should be stated here explicitly.
References:
In the text, references should be cited with Arabic numerals in brackets, numbered in the order cited. In the references section, the references should be numbered and listed in order of appearance in the text. List all authors if there are less than or equal to six authors. List the first three authors followed by ¡°et al.¡± if there are more than six authors. If an article has been published online, but has not yet been given an issue or pages, the digital object identifier (DOI) should be supplied. Journal titles should be abbreviated in the style used in Index Medicus. Other types of references not described below should follow The NLM Style Guide for Authors, Editors, and Publishers [8].

Tables
Tables should be constructed simply and should not duplicate information found in the figures. Each table should have a title, begin on a new page, and be numbered with an Arabic numeral in the order of its citation in the text. If numerical measurements are given, the unit of measurement should be included in the column heading. The statistical significance of observed differences in the data should be indicated by the appropriate statistical analysis. All nonstandard abbreviations should be defined in footnotes. Lower case letters in superscripts a), b), c) ... should be used for special remarks.
Figures
Only high-resolution figure files (preferably 600 dpi for color figures and 1200 dpi for line art and graphs) should be submitted. Figure images should be provided in EPS or TIF format, although the JPEG format is allowed for color figures. The smallest parts of a figure should be legible when they are reduced to the final print size. Each figure should be saved as a separate electronic file. Symbols, arrows, or letters used in photographs should contrast from the background visually. The legend for each light microscopic image should indicate the stain used and the level of magnification. Electron micrographs should have an internal magnification scale marker. All types of figures may be reduced, enlarged, or trimmed for publication by the editor.
CASE REPORTS
Case reports will be published only in exceptional circumstances, when they illustrate a rare occurrence of clinical importance. Case reports should address issues of importance to medical researchers and preferably should have helpful illustrations.
The manuscript for a case report should be organized in the following sequence: title page, abstract and keywords, introduction, case report, discussion, acknowledgments, references, tables, and figure legends. The abstract should be unstructured and its length should not exceed 150 words. There should be no more than five figures, including tables, and no more than 10 references.
REVIEWS
Reviews are invited by the editor and should be comprehensive analyses of specific topics. They are organized as follows: title page, abstract and keywords, introduction, body text, conclusion, acknowledgments, references, tables, and figure legends. There should be an unstructured abstract equal to or less than 200 words. The length of the text excluding references, tables, and figures should not exceed 7,500 words.
EDITORIALS
Editorials are invited by the editor and should be commentaries on articles published recently in the Journal. Editorial topics could include active areas of research, fresh insights, and debates in all fields of internal medicine. Editorials should not exceed 2,000 words, excluding references, tables, and figures.
IMAGES OF INTEREST
The purpose of the Image of Interest is to present state-of-the-art imaging that assists in the evaluation of unusual features of common conditions or in the diagnosis of unusual cases. Images should be pathologic and radiographic with high quality and illustrate the full spectrum of the disorder.
The manuscript for Image of Interest should be organized in the following sequence: the title, a summary of the presentation (cardinal features and key laboratory results will be described briefly), the imaging features (particularly those that lead to diagnosis or which are critical for management), discussion (brief discussion of the disease or the diagnostic or therapeutic process), and the full names and institutional affiliations of authors. There should be no more than two figures and five authors and they should not exceed 300 words in total.
LETTERS TO THE EDITOR
Letters to the Editor will be the rapid publication of new findings of unique importance in clinical settings that lead to the new direction or a short and concise communication commenting on a recently published article in the KJIM.
The manuscript for Letters to the Editor should be organized in the following sequence: the title, the main body of Letters to the Editor (not divided into separate sections entitled introduction, methods, results, or discussion), keywords (not more than 3), the full names and institutional affiliations of all authors, references, tables, and figure legends. The main body should not exceed 1,500 words, but abstract is not required. There should be no more than three figures, including tables, and no more than five references.
