These guidelines are based on the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals”, developed by the International Committee of Medical Journal Editors. You can also read COPE (Committee on Publication Ethics) guidelines, WAME (World Association of Medical Editors) recomendations, ORI (the Office of Research Integrity), CSE (Council of Science Editors), and EASE (European Association of Science Editors) guidelines.
General guideline
- References should be numbered consecutively with Arabic numerals in the order in which they are cited in the text, NOT in alphabetical order.
- The quantity of cited sources should be limited to 30 in original articles, and 60 – in reviews;
- Each reference should be cited in the text, tables, or figures in consecutive numerical order by means of Arabic numerals appeared in square brackets.
- List up ALL the authors or editors in reference list. If there are more than four, list the first three, plus et al. Invert all names –authors, editors, translators, compilers – first & middle initials trailing without periods.
- The names of journals are set in italics and abbreviated according to the List of NLM Catalog by the National Library of Medicine. If a journal is not indexed for Medline, you should use its full title. It is unacceptable to reduce the name of the article or abbreviate the title of the national journal (if it does not have NLM Title Abbreviation or ISO Abbreviation).
- A complete print journal reference includes the following: Authors' surnames and initials; Title of article and subtitle, if any; Abbreviated name of journal; Year; Volume number; Issue number; Part or supplement number, when pertinent; Inclusive page numbers.
- Reference list should be presented in Vancouver as published AMA reference style (AMA style).
- References to non-Latin sources (Russian, Chinese) should be given in Latin script. If an article has the translated title, you should provide an English translation instead of Latin script transliteration [in square brackets].
- If a reference source has the Digital Object Identifier -DOI, it should be provided in the end of the reference. To check if DOI is valid, visit http://search.crossref.org/ or https://www.citethisforme.com. Example:
- Zhang M, Holman CD, Price SD. Comorbidity and repeat admission to hospital for adverse drug reactions in older adults: retrospective cohort study. New Engl J Med. 2009;338:a2752. doi: 10.1136/bmj.a2752
Guidelines for presenting references to non-English and non-Latin sources
If an article is presented in Latin script language (German, French, Finnish, Danish, Italian, etc.), it should be cited in original language:
- Ellingsen AE, Wilhelmsen I. Sykdomsangst blant medisin- og jusstudenter. Tidsskr Nor Laegeforen. 2002;122(8):785-787. (In Norwegian).
If an article is presented in non-Latin script – in Cyrillics (Russian), Chinese, etc., you must transliterate the reference into the English alphabet. Transliteration in BSI standard is given in accordance with original stylistic. If an article has the translated title, you should provide an English translation instead of Latin script transliteration [in square brackets]. For journal articles, you need not translate the journal title: give the transliterated title in BSI standard ((if it does not have NLM Title Abbreviation or ISO Abbreviation), then – imprint details: year;volume(issue):pages. In the end, you should indicate the original language of an article (in round brackets), e.g.: (In Russ.). Afterward, provide DOI, if available. Example:
- Grigoryan OR, Sheremet'eva EV, Andreeva EN, Dedov II. Planirovanie beremennosti u zhenshchin s sakharnym diabetom. Vestnik reproduktivnogo zdorov'ya. 2011;(1):23-31. (In Russ).
- Belaia ZE, Rozhinskaia LY, Mel'nichenko GA, et al. [The role of prolactin gradient and normalized ACTH/prolactin ratio in the improvement of sensitivity and specificity of selective blood sampling from inferior petrosal sinuses for differential diagnostics of ACTH-dependent hypercorticism.] Problemy endokrinologii. 2013;59(4):3-10. (In Russ). doi: 10.14341/probl20135943-10.
