Authors Guidelines

The Lebanese Medical Journal (LMJ) publishes peerreviewed 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 and letters to the editor.

As the official journal of the Scientific Committee of the Order of Physicians in Lebanon, LMJ may publish 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.

All manuscripts will be sent for peer evaluation. However, the decision regarding acceptance for publication will be made by the editorial board. If a manuscript is accepted for publication, it will be necessary for the authors to transfer copyright. The assignment of copyright must accompany each 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 Order of Physicians.


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 is not accepted for authorship, but may be recognized separately in the “Acknowledgments.” Editors may require authors to justify the assignment of authorship.

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

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 discussed below.”

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.”


Manuscripts should be submitted here:

Manuscripts should be typed doubled-spaced on the recto of 21 x 27.9 cm white paper with margins of at least 2.5 cm with no more than 28 lines of 67 characters each per page. 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 starting with page one on the title page and including all pages of references, tables and figure legends.


Full manuscripts (original articles and reviews) should be limited to 5000 words (about 14 double-spaced typed pages) plus abstracts, references and a maximum of eight figures and/or tables. Case reports should be limited to 2500 words (about 7 double- spaced typed pages) and should include an introduction, case description, discussion, 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 author to whom communications, proofs and requests for reprints should be sent. Authors should include a fax number and an e-mail address (if available) where they can be reached.


An abstract in English and French of 100 to 200 words for articles (including reviews) or expanded abstracts, should be typed double-spaced on a separate page. It should cover the main factual points, including statements of the problem, methods, results, and conclusions. The abstract should be accompanied by a list of three to five key words for indexing purposes.


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 [1]. 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.

For journals :

  • Names and initials of first names (capital letters). Names of all authors when six or fewer should be cited. In excess of six, only names of the first three authors should be reported followed by the term “et al.”
  • Title of the article in its original language
  • Name of the Journal according to its abbreviation in the Index Medicus ; if it is not present in the International Committee of Medical Journal Editors or Index Medicus, the name should be mentioned in full.
  • Year – Semi colon (;) – Volume – Colon (:) – First and last page of the article

Tables should be typed double-spaced on separate sheets of 21 x 27.9 cm paper. Oversized paper should not be used unless absolutely necessary. Each table must have a title.


Each illustration or graph, numbered as in the text, should be accompanied by a title and a legend. All legends should be present on the same paper. Do not type the title legend on the illustration. The name of the author and the number of the illustrations and the mention “UP” should be mentioned on a paper, pasted on the back of each illustration. Illustrations should be professional, in black and white. Slides and radiologic films should be converted to photographic pictures. For color illustrations, printing fees are paid for by the authors. Any illustration from previous works should be accompanied by the written permission of both the author and editor and this should be mentioned in the legend.


Names of individuals or institutions who have partly contributed to the work may be mentioned in this section. Pharmaceutical companies should be acknowledged only if they provided experimental drugs or drugs not present in the country where the work was done. Authors are responsible for obtaining written permission from all individuals or institutions who participated in the work and who are named in an acknowledgment, if applicable, since readers may infer their endorsement of data and conclusions. The corresponding author must include the following statement in the cover letter : “I have obtained written permission from all persons named in the Acknowledgments.” Funding and support for research projects should be included in the acknowledgments section.


In case reports, a written statement of consent from patients (parents or legal guardians for minors) should be obtained whenever the patients are identified or photographs are published.


Letters to the Editor are considered for publication (subject to editing and abridgement) provided they do not contain material that has been submitted or published elsewhere. They should not be signed by more than three authors.
