7. AUTHOR'S SUMMARY (ABSTRACT)

An abstract is the basic information source for Russian and foreign information systems and databases. Despite its necessary brevity, an abstract, like a business card, is meant to be exhaustive. Judging from the abstract, the editor decides whether or not the article is worth reviewing. After the article is published, most potential readers (up to 95% by some estimates) will not read beyond the abstract. Thus, it should be able to explain the essence of the study to the reader and entice him/her into obtaining a copy of the full paper for more details. The size of the abstract depends on the amount of information in the article, its scientific value and/or practical importance, however, has to lie within the range of 200-250 words.

Structured abstract
A structured abstract is an essential part of any scientific article that contains experimental or quasi-experimental results, empirical evidence, or systematic review. Its informative value is usually higher than that of an ordinary unstructured abstract. It may be also easier to read and remember. Moreover, a structured abstract ensures higher visibility of the article in international databases, which ultimately influences its citation potential.
A structured abstract should include five sections in chronological order: Rationale, Aim, Methods, Results, and Discussion.

RATIONALE – a brief (1-3 sentences) description of the problem that necessitated the study. The problem can be characterized by its scale, mediated effects, and/or lack of scientific knowledge.

AIM – this section is to define the primary aim, or the main question of the study. Please, note that the aim should be as concrete as possible without boiling down to overall comparisons.

METHODS – this section is meant to provide the following information: 1) subject details (like whether the participants were diseased or healthy), 2) control group details if any, 3) inclusion criteria, 4) performed interventions, 5) study site and 6) duration, 7) outcomes (including measures that can be taken to determine their correspondence with the primary aim) and 8) evaluation methods. The necessity of specifying statistical tests and software will be addressed individually by the editor.

RESULTS – this section should provide further details on study participants (such as the number of those enrolled and those who completed the study as well as some major characteristics of the latter) and evaluate the outcomes that correspond with the primary aim. It is possible to present the results from 2-3 subgroups divided by age, sex, clinical features, etc. Adverse effects, if any, must be reported. Statistical measures (p value) should be given with an accuracy of three decimal places. When investigating multi-criteria relationships (e.g. one dependant and several independent variables), please, provide the results of multifactorial analyses.

CONCLUSION – a summary of study results that correspond with its primary aim (1-3 sentences). Authors are advised to avoid excessive generalization and balance their appraisal of positive and negative effects of an intervention.

A structured abstract should not exceed 250 words. Appropriateness of a larger abstract is discussed individually.
Commercial names of medical products are not allowed in the abstract.

Randomized trial
When reporting the results of a randomized trial, the CONSORT Statement should be complied with. Thus, an abstract is to include the following sections:
 - study DESIGN
 - METHODS
participants
interventions
objectives or study hypotheses
outcomes
randomization sequence generation
blinding (masking) (if applicable)
 - RESULTS
number of randomized participants
numbers analyzed
outcomes and estimation (at the primary endpoint)
adverse events
 - CONCLUSION
 - study number (registration number; e.g. at clinicaltrials.com)
 - funding source

Systematic review
Abstracts of systematic reviews should follow PRISMA recommendations (for reviewing randomized trials) and include the following sections:
- AIM or OBJECTIVES
 - METHODS
inclusion criteria
data sources
study eligibility criteria
 - RESULTS
review of relevant studies
synthesis of results
effect and sensitivity analysis
 - DISCUSSION
summary of evidence and analysis (consistency, accuracy, generalizability, risk of bias)
interpretation of results
 - funding source
 - study number (registration number; e.g. at clinicaltrials.com)

Unstructured abstract
Non-systemic reviews, case reports, and opinion articles usually have unstructured abstracts. Narrative logic should, however, remain: one proceeds from presenting the problem to suggesting a solution and describing own results. Unstructured abstracts should not exceed 150 words.

Keywords should reflect the topic of the article. One can use some particular terms from the text, key terms in the field, or other relevant expressions able to improve search results. It is not recommended to repeat words from the title.

8. TABLES DESIGN. All tables should be enumerated and named. Clipped words are not allowed. Data in the table must be coincident with corresponding data in the text and treated statistically. The tables may be given either in the text, or on separate pages.
Signatures and all text data must be sent in Russian and English!

9. REFERENCE LISTS are to be prepared in accordance with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals of the International Committee of Medical Journals Editors (ICMJE). Reference accuracy guarantees that the citations will be taken into account when assessing scientific public activity of the corresponding authors and their host organizations.
The maximum number of references for original articles is 30, literature reviews - 60, lectures and other materials – 15. Besides fundamental works, the list should include relevant publications over the last 5 years.
References should be numbered and ordered sequentially as they appear in the text.
In-text reference numbers should be in square brackets.
References to unpublished works are not allowed.
According to new reference guidelines that consider requirements of Web of Science and Scopus indices, bibliographic descriptions for Non-Latin References should be provided in not only their source languages, but also in Latin.
Thus, in order to be included in citation indices and DOI-CrossRef system, reference lists should be displayed as described below.
For example:

When referencing a journal article, always include the DOI (Digital Object Identifier in the CrossRef system). DOI search should be done at http://search.crossref.org/ or https://www.citethisforme.com. To start the search, type in the English title of the article. The latter website is able to provide you with not only the DOI, but also a full bibliographic description in AMA style. One should keep in mind that most journal articles (including many Russian-language ones) published after 2013 are registered in the CrossRef system and have a DOI.

Preparing Russian-language references for importation into international citation indices.
1. Journal articles.
Authors’ surnames and initials as well as the English title of the article should be identical to those in the original publication. Journal name that follows should be transliterated according to the BSI standard (can be done automatically at http://ru.translit.net/?account=bsi). Then come publication details (year, volume, issue, and pages). Source language should be indicated in parentheses. At the end of the description, the DOI should be given (if available). For example:
... [Belaia Z, Rozhinskaia L, Mel'nichenko G, Sitkin I, Dzeranova L, Marova E, Vaks V, Vorontsov A, Il'in A, Kolesnikova G, Dedov I.
