Key Words

Provide three to seven keywords separated with semicolons (;). Terms from the medical subject headings (MeSH) should be used
 (see unless the keyword is not available and has no synonymous term in the MeSH database. 

Introduction: State the purpose of the article and summarizes the rationale for the study or observation.


Original research articles: the selection of the observational or experimental subjects (patients or laboratory animals, including controls) should be described clearly. The methods and procedures should be given in sufficient details. Briefly describe established methods with their references. Describe new or substantially modified methods, give reasons for using them, and evaluate their limitations. Identify precisely all drugs and chemicals used, including generic name(s), dose(s), and route(s) of administration.

Randomized clinical trials: should present information on all major study elements, including the protocol, assignment of interventions (methods of randomization, concealment of allocation to treatment groups), and the method of masking (blinding), based on the CONSORT Statement.

Review article: should include a section describing the methods used for locating, selecting, extracting, and synthesizing data. These methods should also be summarised in the abstract.

 Statistics: Specify the statistical software package(s) and versions used. Define statistical terms, abbreviations, and most symbols. Use upper italics (e.g. P< 0.05). For all P values include less than 0.05, 0.01, or 0.001.

Results: The results should be presented in logical sequence in the text, tables, and/or figures. Do not repeat in the text all the data in the tables or figures. Emphasize or summarize only important observations.

Discussion: The discussion should begin by briefly summarizing the main findings, and explore possible mechanisms or explanations for these findings. Emphasize the new and important aspects of your study and put your finings in the context of the totality of the relevant evidence. The limitations of your study should be stated.

Conclusion : Link the conclusions with the goals of the study but avoid unqualified statements and conclusions not adequately supported by the data. 

Acknowledgments: Some contributions need acknowledging but do not justify authorship (vide-infra), such as general support by a departmental chair; acknowledgments of technical help; and acknowledgments of financial and material support, which should specify the nature of the support. This should be included in the title page of the manuscript.

References: References should be numbered by Arabic numerals in parentheses consecutively in the order in which they are first mentioned in the text. The formats of the references should follow Vancouver style. Avoid citing a “personal communication” or unpublished reference. Limit the number of references to less than 30 for original research articles and 40 for review articles.

The commonly cited types of references are shown here, for other types of references such as electronic media, newspaper items, etc. please refer to ICMJE Guidelines (

  • Number tables in Arabic numerals consecutively in the order of their first citation in the text and supply a title for each. Titles in tables should be short but self-explanatory, containing information that allows readers to understand the table's content without having to go back to the text.

  • Give each column a short or an abbreviated heading. Any explanatory matter should be in the footnotes, not in the heading. Explain all nonstandard abbreviations in footnotes, and use symbols to explain information if needed.

  • For footnotes use the following symbols, in this sequence: *, †, ‡, §, ||, ¶, **, ††, ‡‡

  • Identify statistical measures of variations, such as standard deviation and standard error of the mean.

  • If you use data from another published or unpublished source, obtain permission and acknowledge that source fully.

Illustrations (Figures):

  • Figures should be numbered consecutively according to the order in which they have been cited in the text. If a figure has been published previously, acknowledge the original source and submit written permission from the copyright holder to reproduce it. Permission is required irrespective of authorship or publisher except for documents in the public domain. 

  • Letters, numbers, and symbols on figures should be clear and consistent throughout, and large enough to remain legible when the figure is reduced for publication. Figures should be made as self-explanatory as possible. Titles and detailed explanations belong in the legends—not on the illustrations themselves.

  • In the manuscript, legends for illustrations should be on a separate page, with Arabic numerals corresponding to the illustrations. When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, identify and explain each one clearly in the legend.

  • Digital images should be submitted in a suitable format. Figures should be either professionally drawn and photographed, or submitted as photographic-quality digital prints. 

  • For X-ray films, scans, and other diagnostic images, as well as pictures of pathology specimens or photomicrographs, send high-resolution photographic image files.

  • The Journal reserves the right to crop, rotate, reduce, or enlarge the photographs to an acceptable size.


LIMUJ follows the guidelines set by the International Committee  of Medical Journal Editors (ICMJE) and Committee on Publication Ethics (COPE) concerning ethics and scientific integrity. Scientific misconduct such as falsification of data, plagiarism, and untrue authorship are strictly forbidden and may result in the withdrawal of the article even after its publication and hindrance of any future publication in the journal. The author should be aware of the following facts concerning scientific misconduct:

Falsification of data:

Falsification of data of ranges from fabrication of data, suppression and/or distortion of data to selective reporting of findings and omission of conflicting data.

 Plagiarism:   Very briefly, plagiarism may take one of the followings three forms:

  • The use of another person's ideas, processes, results or words without giving appropriate credit. 
  • Self-plagiarism, whereby authors copy large parts of one of their previous manuscripts word-for-word. 
  • Duplicate publication when an author submits a previously-published work as if it were original.


For scientific integrity authorship should be based on the following 4 criteria set by ICMJE organization:

  • Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND 
  • Drafting the work or revising it critically for important intellectual content; AND
  • Final approval of the version to be published; AND 
  • Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

All those designated as authors should meet all four criteria for authorship. Those who do not meet all four criteria should be acknowledged. The authors should provide a short description of each author's contribution in the cover letter submitted with the article.

 Human rights, privacy, and confidentiality

  • For manuscripts reporting medical studies involving human participants, the authors should provide a statement identifying the ethics committee that approved the study, and that the study conforms the (Declaration of Helsinki). 
  • Non-essential identifying details should be omitted otherwise informed consent should be obtained from the patients.

Research involving animals:

The authors should confirm that ethical and legal approval was obtained prior to the start of the study, and state the name of the body giving the approval. Authors should also state whether experiments were performed in accordance with relevant institutional and national guidelines and regulations.


The revised version of the manuscript should be submitted online in a method similar to that used for submission of the manuscript for the first time. While submitting a revised version, there is no need to submit the “First Page” or “Covering Letter” file. Reviewers’ remarks along with point to point clarification should be submitted in a separate file using the journal form. The contributors’ form has to be submitted in original with the signatures of all the contributors within two weeks after acceptance for publication.
