The Ceylon Medical Journal's mission is to stimulate, encourage and empower doctors, researchers and other health professionals to publish high quality research in order to promote evidence based medicine and improve health care. The Ceylon Medical Journal (CMJ) is an open access, peer-reviewed journal.
All authors must read the Ethical Responsibilities of the journal before submitting their articles.
Conflict of interests
The Ceylon Medical Journal requires that all authors declare any relevant financial and non-financial conflicts of interest and the journal publishes those that might influence a readers perception of the paper alongside the paper. The Ceylon Medical Journal requires that all funding sources of the research are declared and published and the role of the funding source in the conception, conduct, analysis and reporting of the research is stated and published.
TYPES OF ARTICLES
The CMJ publishes a wide variety of articles which have relevance to medicine and allied sciences.
Leading articles are solicited by the editors, and are expert opinions on current topics or commentaries on other papers published in the CMJ. They do not usually exceed 1500 words or have more than 20 references. Tables and illustrations are usually not included in leading articles.
Original articles report the results of original research, systematic reviews and meta-analyses. Observational studies (cohort, case-control, or cross-sectional designs) must be reported according to the STROBE statement. Systematic reviews and meta-analyses must be reported according to PRISMA guidelines. Reports of randomised trials must conform to CONSORT 2010 guidelines. Diagnostic accuracy studies must report according to the STARD guidelines. The guidelines on reporting sex and gender information (SAGER) should also be considered. Original articles should have less than 2500 words, 5 tables / illustrations and should include a structured abstract of less than 250 words.
This category includes preliminary reports, novel patient management methods, and reports of new techniques and devices. They should be limited to 1000 words, 3 tables/illustrations and 10 references, and should include an unstructured abstract of less than 100 words.
Acceptance of case reports is based strictly on originality and whether there is an important new lesson to be learnt or a new message from the report. It should not contain more than 750 words, one table / illustration and 5 references. Authorship should be limited to five. Case reports may be accepted as contributions to the picture-story series (not more than 300 words of text, 3 references and 2-3 clear black and white or colour photographs). Case reports must be prepared according to the Consensus-based Clinical Case Reporting (CARE) guidelines.
Perspectives and points of view
The CMJ also welcomes essays expressing opinions, presenting hypotheses, broaching controversial issues, clarifying recent advances in the basic sciences, and essays pertaining to medical education, history of medicine, health politics and patients’ rights. They should not have more than 750 words and 10 references.
The CMJ will also consider for publication letters (less than 400 words, maximum of 3 authors, and maximum of 5 references). These may be in response to a recently published article or a short freestanding piece expressing an opinion.
Criteria for authorship
Only persons who contributed to the intellectual content of the paper should be listed as authors. According to the ICMJE recommendations authorship should be based on the following 4 criteria:
In addition to being accountable for the parts of the work he or she has done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their co-authors.
All those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors. Contributors who meet fewer than all 4 of the above criteria for authorship should not be listed as authors, but they should be acknowledged.
Conflict of interests
Please download and complete a copy of the disclosure form. The form should be signed by all authors. The corresponding author must insert within the submitted manuscript a summary statement under the heading “Conflicts of Interest” which describes authors’ conflicts of interest, sources of support for the work including sponsor names and whether the authors had access to the study data. Authors of a study sponsored by a funder with a proprietary or financial interest in the outcome should include a statement, such as “I had full access to all of the data in this study and I take complete responsibility for the integrity of the data and the accuracy of the data analysis.”
All sources of funding should be declared in the covering letter under the heading “Funding”. Authors must describe the role of the study sponsor(s), if any, in the study design; in the collection, analysis and interpretation of the data; in the writing of the report; and in the decision to submit the paper for publication. If the funder(s) had no such involvement, this should be stated.
In the cover letter give full details on any possible previous publication of any content of the paper. (e.g.)
Previous publication of some content of a paper does not necessarily preclude it being published in the CMJ, but the editors need this information when deciding how to make efficient use of space in the journal, and regard failure of a full disclosure by authors of possible prior publication as a breach of scientific ethics.
For studies involving human participants a statement detailing ethics approval and consent should be included in the methods section. Every research article should include a statement that the study obtained ethics approval (or a statement that it was not required and why), including the name of the ethics committee(s) or institutional review board(s), the number/ID of the approval(s), and a statement that participants gave informed consent before taking part. Proof of approval from an ethics committee must be provided on submission of the manuscript. All clinical trials should be registered in an internationally recognized Clinical Trials Registry and authors should submit the Trial Registration Number along with the manuscript.
For case reports, signed consent by the patients must be submitted with the manuscript. If the person described in the case report has died, then consent for publication must be sought from their next of kin. If the individual described in the case report is a minor, or unable to provide consent, then consent must be sought from their parents or legal guardians. Please use the consent form available here. Sinhala/ Tamil/ English
If consent cannot be obtained because the patient cannot be traced then publication will be possible only if the information can be sufficiently anonymised. Anonymisation means that neither the patient nor anyone else could identify the patient with certainty.
Manuscripts should be submitted with a letter stating
The letter should acknowledge any potential conflict of interest (see Ethical Responsibilities above) and call the editors’ attention to any possible overlap with prior publications. Include the name, full mailing address, telephone number and e mail address of the corresponding author.
Submit an original copy and 3 copies (photocopies are acceptable) of all parts of the manuscript, 3 original glossy prints of all figures, and 2 copies of the cover letter. All submissions must be accompanied by an electronic copy of the manuscript and illustrations. The manuscript should be mailed, with adequate protection for figures, to the Editors, Ceylon Medical Journal, No: 6 Wijerama Mawatha, Colombo 7, Sri Lanka. Manuscripts could also be submitted directly at the office of the Sri Lanka Medical Association.
Manuscripts can also be submitted on-line at the journal site. (http://cmj.sljol.info/).
Address all editorial correspondence to: The Editors, The Ceylon Medical Journal, No: 6, Wijerama Mawatha, Colombo 7, Sri Lanka.
PREPARATION OF MANUSCRIPT
The CMJ will consider all manuscripts prepared in accordance with the uniform requirements for manuscripts submitted to biomedical journals developed by the International Committee of Medical Journal Editors. A summary of these and the requirements of the CMJ are given below.
All parts of manuscript, including tables and figure legends, must be typed with double spacing. The computer language must be set to English (UK).
References must also be double spaced. Manuscripts should be typed in capital and lower case letters, on white paper of A4 size (212x 297 mm).
Arrange components in the following order: title page, abstract, text, references, tables in numerical sequence, and figures in numerical sequence. Begin each component on a separate page.
Number all pages consecutively, starting with the title page.
The British Medical Journal, Lancet and Annals of Internal Medicine are recommended to authors as guides to style, clarity of presentation and conciseness.
Name of drugs and instruments
Generic (nonproprietary) names should be used for all drugs. When proprietary brands are used in research, include the brand (proprietary or trade) name and the name of manufacturer in parentheses after the first mention of the generic name in the Methods section. Thereafter the generic name should be used.
Instruments may be referred to by proprietary name, giving the name and location of the manufacturer in the text in parentheses.
Abbreviations and symbols
Use only standard abbreviations; use of nonstandard abbreviations can be confusing to readers. Avoid abbreviations in the title of the manuscript. The spelled-out abbreviation followed by the abbreviation in parenthesis should be used on first mention unless the abbreviation is a standard unit of measurement.
Units of Measurement
Measurements of length, height, weight, and volume should be reported in metric units (meter, kilogram, or litre) or their decimal multiples.
Temperatures should be in degrees Celsius. Blood pressures should be in millimeters of mercury.
Headings in text
Use only two levels of headings in the text. Clearly indicate the levels of headings by using different typographic conventions. Keep headings short.
The title page should contain the following:
The abstract should provide the context or background for the study and should state the study's purpose, basic procedures (selection of study participants, settings, measurements, analytical methods), main findings (giving specific effect sizes and their statistical and clinical significance, if possible), and principal conclusions. Clinical trial abstracts should include items that the CONSORT group has identified as essential. Clinical trials should give clinical trial registration number at the end of the abstract. Authors are recommended to consult the SAGER guidelines for the reporting of sex and gender information.
Abstract should include the sub-headings: Introduction, Objectives, Methods, Results and Conclusions. Number of words should be less than 250 words. Brief Reports should have an unstructured abstract limited to 150 words.
The text should contain the following categories; Introduction, Methods, Results, Discussion, Acknowledgements, Conflicts of Interests, References, Tables and Figures. Under a subheading "Conflicts of Interests ", all authors must disclose any financial and personal relationships with other people or organisations that could inappropriately influence (bias) their work. If there are no conflicts of interest, authors should state that “There are no conflicts of interest”.
Number references in the order in which they are first cited in the text. Use Arabic numerals within parentheses e.g. . Note that from 2015 the CMJ requires the PubMed abbreviation of the journal title (or a similar abbreviation if the journal is not indexed in PubMed) NOT the COMPLETE name of journal. Include year, volume and first and last page numbers.
References to articles or books accepted for publication but not yet published must include the title of the journal (or name of the publisher) and the year of expected publication. Unpublished work (personal communication) may be cited by inserting a reference within parentheses in the text; authors must submit a letter of permission from the cited persons to cite such communications.

All tables must be typed double-spaced. Tables should be numbered with Arabic numerals, in the order in which they are cited in the text. A table title should describe concisely the content of the table.
Figures and illustrations Figures or illustrations should be professionally drawn or prepared digitally. A high resolution (300dpi) digital copy of the figure or illustration should be submitted. Lettering should be uniform in style. Free hand or typewritten lettering is not acceptable. Number the figures in the order in which they are cited in the text. Colour figures may be submitted and will be published if essential. Three colour prints should be submitted for each figure.
Photographs Three glossy prints and a high resolution (300 dpi) jpg format softcopy should be provided. Photomicrographs should have scale markers that indicate the degree of magnification. Indicate on a label the name of the first author of the paper and the figure number: then paste the label on the back of the photo. Do not mount photos on backing board.
Colour photographs are included only if publishing costs are borne by the author (Rs. 7 500/=). Authors may also be asked to contribute towards the cost of publishing black and white photographs (Rs. 2 500/=).
Legends for figures
Reduce the length of legends by using partial sentences. Explain all abbreviations and symbols on the figure, even if they are explained in the text. Stain and magnification should be given at the end of the legend for each part of the figure. If there is no scale marker on the figure, the original magnification used during the observation should be given, not that of the photographic print.
Acknowledgements Acknowledge only persons who have contributed to the scientific content and provided financial or technical support. Authors must submit written permission from persons acknowledged for other than financial or technical support.
