Author’s Guidelines

The LMJ asks authors and reviewers to follow the recommendations of the International Committee of Medical Journal Editors (ICMGE), to create and distribute accurate, clear, reproducible, unbiased medical journal articles.

The Lebanese Medical Journal (LMJ) publishes open-access free of charges peer-reviewed articles on all aspects of medicine and related fields. Authors are invited to submit original research articles (either clinical or experimental), review articles, case reports, medical ethics, history, and letters to the editor.

As the official journal of the Scientific Committee of the Order of Physicians in Lebanon, LMJ may publish (proceedings of) abstracts of reports presented at annual scientific sessions of Scientific Societies and may, from time to time, publish expanded abstracts as short papers comprising the proceedings of annual meetings upon invitation.

All manuscripts will be sent for peer evaluation through a double-blind review process. However, the decision regarding acceptance for publication will be made by the editorial board, within a mean-time of 2 to 3 months. If a manuscript is accepted for publication, it will be necessary for the authors to transfer copyright (copyright.pdf). The assignment of copyright must accompany each accepted manuscript, submitted to the Lebanese Medical Journal. No part of the published material may be reproduced elsewhere without written permission from the publisher or the Lebanese Order of  Physicians (LOP).


All persons designated as authors should qualify for authorship. Each author should have participated sufficiently in the work to take public responsibility for the contents. Partial contribution to the work and/or performing the statistics are not accepted for authorship but may be recognized separately in the “Acknowledgments.” Editors may require authors to justify the assignment of authorship.

The ICMJE recommends that authorship be based on the following 4 criteria:

1. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND

2. Drafting the work or revising it critically for important intellectual content; AND

3. Final approval of the version to be published; AND

4. 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.

The cover letter includes (A) a statement on authorship responsibility and (B) a Statement on financial disclosure and (C) a statement on copyright transfer. Each of those three statements must be signed by the corresponding author on behalf of all the authors.

The corresponding author is the one individual who takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process. The corresponding author should be available throughout the submission and peer-review process to respond to editorial queries in a timely way and should be available after publication to respond to critiques of the work and cooperate with any requests from the journal for data or additional information should questions about the paper arise after publication.

A–Authorship responsibility

“I certify that I have participated in the conception and design of this work and the analysis of the data (when applicable), as well as the writing of the manuscript, to take public responsibility for it. I believe the manuscript represents valid work. I have reviewed the final version of the submitted manuscript and approve it for publication. Neither this manuscript nor one with substantially similar contents under my authorship has been published or is being considered for publication elsewhere, except as described in an attachment. If requested, I shall produce the data upon which the manuscript is based for examination by the editors or their assignees.”

B – Financial disclosure

“I certify that any affiliation with or involvement in any organization or entity with a direct financial interest in the subject matter or materials discussed in the manuscript (e.g., employment, consultancies, stock ownership, honoraria, expert testimony) are declared below.” When the paper is accepted, all co-authors must fill and sign the ICMJE Form for Disclosure of Potential Conflicts of Interest (coi-disclosure.pdf).

C – Copyright transfer

“The author(s) undersigned hereby transfer(s), assign(s) or otherwise convey(s) all copyright ownership to the Order of Physicians in Lebanon in the event that such work is published by the Order of Physicians in Lebanon.”


Authors should seek approval to conduct research from an independent local, regional, or national review body (e.g., ethics committee, institutional review board). This must be stated in the cover letter and in the Methods section.

All investigators should ensure that the planning conduct and reporting of human research are in accordance with the Helsinki Declaration as revised in 2013 (

When reporting experiments on animals, authors should indicate whether institutional and national standards for the care and use of laboratory animals were followed. Further guidance on animal research ethics is available from the International Association of Veterinary Editors’ Consensus Author Guidelines on Animal Ethics and Welfare (`

Authors must follow reporting guidelines for different study designs: CONSORT ( for randomized trials, STROBE for observational studies (, PRISMA for systematic reviews and meta-analyses (, and STARD for studies of diagnostic accuracy (

LMJ requires registration of clinical trials in a public trials’ registry at or before the time of first patient enrollment as a condition of consideration for publication. Authors must publish the trial registration number at the end of the abstract.


Manuscripts should be submitted here: LMJ encourages authors to provide an ORCID when submitting a manuscript. This takes around 2 minutes to complete. Please see resources on ORCID (

Manuscripts should be typed single-spaced with margins of at least 2.5 cm. They are received with the understanding that they have not been previously published and are not currently under consideration for publication in any other journal. Manuscripts will be acknowledged upon receipt. Manuscript pages should be numbered including all pages of references, tables, and figure legends.


Full manuscripts (original articles, reviews, medical ethics, and history) should be limited to 5000 words plus abstracts, a maximum of 60 references, and a maximum of eight figures and/or tables. Case reports should be limited to 2500 words and should include an introduction, case description, discussion, a limit of 15 references, and one (1) table or figure. Letters to the editor should be limited to 1500 words, 5 references, and one (1) table or figure. Each section should be typed on a separate page.


In addition to the title, the full names, degrees, and hospital or university affiliation of each author should be included. If an author’s present affiliation is different from that under which the work was done, both should be given. A short title of no more than 50 characters for use as a running head should also be given. At the bottom of the title page, include the exact postal address and the telephone number of the corresponding author to whom communications, proofs, and requests for reprints should be sent. Authors should include a fax number (if available) and an e-mail address where they can be reached.

The title page should include sources of support, word count, and several tables and figures.


An abstract in English of a maximum of 250 words for articles (including reviews) or expanded abstracts, should be presented as a separate Word document. It should cover the main factual points, including statements of the problem and aim of the study, methods, results, and conclusions. The abstract should be accompanied by a list of three to six keywords for indexing purposes.


The text of articles reporting original research is usually divided into Introduction, Methods, Results, and Discussion sections. Appropriate headings and subheadings should be provided in the methods, results, and discussion sections. The text should be clear and concise. Since the readership of LMJ spans many disciplines, jargon should be avoided, as it may not be familiar to some readers. Likewise, acronyms such as ECG, LVH, can be used if they are spelled out in full when first cited. Only measurements are abbreviated without expansion and should follow the form recommended by the International Committee of Medical Journal Editors (ICMJE). Suppliers of specific instruments or drugs should be noted, citing both the company name and city. Generic names should be given in parentheses following any trademark drug names.


References should be limited to articles mentioned in the text and indicated by numbers; the latter should follow the order of appearance of articles in the text. Abstracts should be identified as such in the reference list. References should follow the norms established by the International Committee of Medical Journal Editors (ICMJE).
