Background (research significance) – one or two sentences
Aim — one phrase describing the main aim of the study

4.5. Main body of the article
4.5.1. The main body should be simple and clear, without a long historical introduction, unreasonable repetitions, neologisms and scientific jargon. Generic names should be used when referring to medications; in order to clarify the name of the medication you can use website www.grls.rosminzdrav.ru. Try to avoid a large number of abbreviations in the text. All abbreviations should be preceded by the full name of the original term with the abbreviation in brackets, e.g. "Magnetic Resonance Imaging (MRI)". In general, the text of the article should not contain more than 5-7 abbreviations. Abbreviations met in the text only once or twice are unnecessary. If the article contains more than 7 abbreviations, or they are often encountered, after the abstract, before the main text, you should include the fragment "Accepted abbreviations" and describe all the abbreviations used.
4.5.2. Authors are encouraged to keep the presentation concise, and the results obtained by authors should be clearly differentiated from relevant data in the literature and their interpretations.
4.5.3. The following order is recommended:
Introduction and background/research significance;
Materials and methods
Results
Discussion
Conclusion
Additional information
Reference list
Authors information
Tables
Figures
4.5.4. The title, aim and conclusions of the article should correspond to each other. Conclusions must contain relevant evidence from the data obtained in the work.

Only studies that are directly relevant to the topic should be cited, excluding data and conclusions presented in the article itself.
4.5.6. Describing Materials and Methods of research detailed information should be given about:
the type of study: literature review, experimental, descriptive, analytic (case-control or cohort), or cross-sectional study (single point in time), case report, etc. For randomised trials, a randomization method must be specified. A study protocol should be set out as clearly as possible
the time of the study, its duration (the study years, participating centres)
the method of selecting patients or experimental animals for observation and experiments (including those for control groups), their age, sex and other relevant characteristics
the methods, apparatus (with its manufacturing company and country or city) and all procedures in sufficient detail to allow other investigators to reproduce the results. The quantitative and qualitative characteristics of patients (examined) are given.
cite references to established methods. Identify precisely all drugs and chemicals used, their dosage and administration routes. The trade name of a drug and a manufacturer can be identified in this section in brackets after a generic name of the drug. But it cannot be repeated over and over again throughout the article — this is an advertisement!
the statistical methods: all statistical criteria used should be mentioned (e.g. Student’s t-test for independent samples, Pearson correlation coefficient), statistical abbreviations should be expanded, e.g. Me (median), etc. It is insufficient to refer only to the used statistical software. The specified statistical processing methods should make it possible to solve the tasks set in the work (to determine the dependencies, show the relationships and their degree, etc.)
the compliance of procedures presented by authors with ethical principles with the name of Ethics Committee that approved the research (when studying treatment methods, invasive diagnostic procedures involving human subjects or animals, protocol numbers and dates).
4.5.7. All clinical trials should be conducted in accordance with the ethical principles of Good Clinical Practice and comply with the requirements of Federal Law No. 61 “On the Circulation of Medicines” (2010), as well as other applicable laws of the Russian Federation: Decree by the Ministry of Health of Russia as of 04.01.2016 №200n "On approval of the rules of good clinical practice", National Standard of the Russian Federation GOST R 52379-2005 "Good Clinical Practice", Federal Law № 323-FZ as of 21.11.2011 "On public health protection in the Russian Federation" and other legal acts that are in force.

Participants in the study must be familiar with the aims and main purpose of the study, with all the diagnostic procedures, treatments and rehabilitation plans that are included in the study (laboratory, functional, radiation and other diagnostic methods, medical appointments, and manipulations not provided in the standard treatment), after which the patient must sign Voluntary Informed Consent to participate (Voluntary Informed Consent to participate in the study and the provision of routine medical practice are not one and the same!). If the research procedure includes radiation, then it is advisable to describe the procedures and the exposure dose in the "Material and Methods" section.
4.5.9. Confidential information about patients; photographs, names, medical document numbers and other sources by which the patient's identity can be identified; must not be included in the article.
4.5.10. Results of the research should be presented in the text, tables and figures following a logical sequence and avoiding repeating in the text information presented in tables or figures, only important observations should be emphasized or summarized.
4.5.10.1. All Tables and Figures must be referred to in the main body of the text in the appropriate place.

Reporting the results only as arithmetic mean or median is not enough! The level of significance is recommended to be reported rounded to the third decimal place: e.g., p=0.023 instead of p<0.05. All statistical data submitted for publication must comply with the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals". Mathematical formulas should be constructed using the standard tools of MS Word, scrutinized and placed in the text. Units of measure should be given in SI units, temperature in degrees Celsius, blood pressure in mmHg.
4.5.13. In the Discussion section novel and important aspects of the study, possibilities for the implementation of the obtained results also in further studies, as well as their limitations should be emphasized. Results of the study should be critically compared with other studies in this field. This part should not duplicate or replace the "introduction" section, but should have the task of explaining the data obtained and highlighting their novelty, confirming its assumptions based on already known facts obtained by other authors.
4.5.14. An explanation by authors of the results obtained is encouraged.
4.5.15. It is acceptable to combine the last two sections into one — "Results and Discussion".
