  • Background:  Relevant background information and the context of the problem that was investigated.
  • Objective: A one-or two-sentence description of the purpose of the study
  • Methods: Outline of study design, study population, subject/participant selection, analytical methods, and data analysis.
  • Results: What was found based on the data analysed. Give specific data and their statistical significance if possible.
  • Conclusion: Provide a one-or two-sentence description of the conclusions, based on the results.
  • Keywords: Authors should provide a maximum of five key words for the article.

Original articles should conform to the following format.

This should start on a fresh page and should provide a brief review of the literature related to the objective of the paper. A short statement on the aim of the work should be presented.

Materials and Methods

This should be sufficiently detailed (with references where possible) to permit other researchers to replicate the study. Sources of materials used must be given and statistical methods must be specified by reference unless non-standard ones are used. For investigations of human subjects, authors should state in the methods section the manner in which informed consent was obtained from the study participants, and describe how the study investigators protected the right of participants as described in the Declaration of Helsinki. Also the IRB and/or institution(s) that gave the ethical approval from must be mentioned.

These must be clearly and concisely provided, with the help of appropriate illustrative material Tables and/or figures. Do not use Table and figure to present the same data.

This section should relate the findings with existing relevant studies. It should cover the implication of the findings and limitations of study. Recommendations may be given, but unjustified speculation should be avoided. 


This should be brief and presented on a separate page. Financial support, technical assistance and advice may be acknowledged.

Conflicts of interest and other disclosures.

Authors must confirm upon submission that the manuscript is an original work, and has not been submitted for publication elsewhere. Additionally, authors must explicitly state any potential financial or other conflicts of interest in a cover letter accompanying submission of their manuscript. Finally, the corresponding author will need to verify that each author listed has seen and approved the orm and content of the submitted manuscript.

Ethics approval and consent to participate

Manuscripts reporting studies involving human participants, human data or human tissue must: include a statement on ethics approval and consent (even where the need for approval was waived), include the name of the ethics committee that approved the study and the committee’s reference number if appropriate.

In addition, studies involving animals must include a statement on ethics approval. If your manuscript does not report on or involve the use of any animal or human data or tissue, please state “Not applicable” in this section.

If your manuscript contains any individual person’s data in any form (including individual details, images or videos), consent for publication must be obtained from that person, or in the case of children, their parent or legal guardian. All presentations of case reports must have consent for publication.

You can use your institutional consent form if you prefer. You should not send the form to us on submission, but we may request to see a copy at any stage (including after publication).

Availability of data and materials

All manuscripts must include an ‘Availability of data and materials’ statement. Data availability statements should include information on where data supporting the results reported in the article can be found including, where applicable, hyperlinks to publicly archived datasets analysed or generated during the study. By data we mean the minimal dataset that would be necessary to interpret, replicate and build upon the findings reported in the article. We recognise it is not always possible to share research data publicly, for instance when individual privacy could be compromised, and in such instances data availability should still be stated in the manuscript along with any conditions for access.

Changes to authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.


Only in exceptional circumstances will the Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended.

Articles in press (accepted for publication), may be included and cited appropriately indicating name, volume and year in which journal would appear.
