Article types and length
Authors are welcome to submit their original empirical research or commentary in any field of medicine. The amount of text, figures and tables should be reduced to minimum. Please keep in mind that the shorter the article, the more likely it will be read and cited by other researchers. The maximum word limits are as follows:

Commentary <500 words, a response to an article previously published in EJTCM
Short communication <1500 words, describes preliminary results of original research
Review article <4000 words
Original article <4000 words
Meta-analysis <4000 words
Case reports are not accepted.
The Editor may accept longer manuscripts only in exceptional and justified circumstances.

Manuscript selection and peer review
All submitted manuscripts are evaluated by the Editor for suitability for consideration for publication in the EJTCM. Potentially acceptable manuscripts will undergo a double-blind review process (detailed analysis by two reviewers with expertise in the specific field of medicine). All revised manuscripts are carefully re-examined with no guarantee of acceptance, and authors will have two opportunities to make revisions to the same manuscript. Final acceptance is based on originality, significance, documentation of conclusions, and form of presentation.
Authors may suggest peer reviewer/s who are experts in the particular field of research, however the EJTCM does not guarantee which reviewer will complete the review.

Plagiarism
All submitted manuscripts are verified using plagarism detection software such as iThenticate and Crossref.

Language Please write your text in standard English (American or British usage is accepted, but not a mixture of them). Authors who feel their English language article may require editing to eliminate possible grammatical or spelling errors and to conform to correct scientific English may wish to contact language.ejtcm@gumed.edu.pl for a referral to a professional medical writer.
The services of a medical writer are not free of cost.

Article structure
The article text should be divided into clearly defined sections. Each section should be given a brief heading. The organization of review articles should be appropriate to the content of the review. The article must be typed double-spaced.

• Introduction
  State the objectives of the work and provide an adequate background that orients the general scientific reader to the topic. Avoid a detailed literature survey or a summary of the results.
• Material and methods
  Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described. Include a description of statistical methods used.
• Results
  Results should be clear and concise. Results may be presented in tables or figures that should not duplicate the text.
• Discussion
  Synthesize the results into a cohesive story in the context of the published literature. Set forth the major conclusions of the authors. Do not repeat information from the Introduction or Results section. Avoid extensive citations and discussion of published literature.

Title page

• Title
  Please keep your manuscript’s title short. Avoid abbreviations.
• Author names and affiliations
  Include the names and affiliations of the author(s). Provide the full name of each affiliation.
• Corresponding author
  Indicate the address of the author to whom correspondence and reprint requests should be directed. The corresponding author is expected to handle correspondence at all stages of the review process and post-publication. Ensure that phone numbers (with complete country and area code) are provided in addition to the e-mail address and the complete postal address.
• Running head and abbreviations
  Include an abbreviated title (45 characters or less). Abbreviations should be kept to a minimum and only universally understood abbreviations are allowed. Only standard chemical or nonproprietary names of medications should be used. All abbreviations must be defined when used for the first time in the abstract and the body of the manuscript.

Abstract
An abstract of 200 words or less should orient the reader to the purpose of the research, the principal results, and major conclusions, all in one paragraph without subheadings. It should be easily understood without reference to the text. Place essential findings and keywords in the first two sentences of your abstract.

Keywords
Please include at least 3 but no more than 5 keyword phrases and subject headings.

Acknowledgements
This is the section after the Discussion and before the References, dedicated to recognizing the names of non-authors who have been helpful in the research described in the manuscript and/or in creating the manuscript. In addition, this section must contain disclosure of all sources of financial support for the described research, any potential conflicts of interest, and clinical trial registry information.

Examples of financial relationships that lead to conflicts of interest:
compensation for services (e.g., employment, consulting fees, honoraria, expert testimony, advisory boards, speaker's bureau), equity interest (e.g., stocks, stock options, bonds, or other ownership interests), intellectual property rights (e.g., patents filed or pending, copyrights, royalties), direct financial support of the research project (e.g., grants, contracts, or material support).

References
All references must be cited in the order they appear in the text (chronologically) and numbered using brackets (e.g. [1] ) and listed, in the order cited, after the Acknowledgments section. Authors are responsible for the accuracy of their references. Journal articles listed in the Reference section of the manuscript must also contain links to their online versions (this is required for indexing in PubMed).
All references must be formatted in accordance with the Vancouver (brackets) format, e.g.:
