Articles requirements

ARTICLE DESIGN

The text is printed with 1.5 line spacing, without hyphens, in Times New Roman, 14-point font, in the MS Word text editor, and saved in .doc or .docx format. Paragraph indent – 1.25 cm using the "Paragraph" menu. Margins of 25 mm on all sides, with no headers, footers, or page numbering.

Punctuation and Typography

• In the middle of a sentence, use an en dash "–" with spaces on both sides.
• Use an en dash without spaces between numbers: 2019–2020.
• A hyphen "-" is used between compound words: physician-dentist, research-based.
• An em dash "—" is not used in scientific articles.
• Separate a number from a percent sign using a non-breaking space Ctrl + Shift + Space: 37 %
• In the English version of the manuscript, the integer part of the number is separated from the decimal with a period: 3.14

Quotation marks: in Ukrainian text use «Word», in English text use "Word".

References are cited as numbers in square brackets in ascending order, separated by a comma and a space: [3, 6].

Abbreviations and acronyms must be first mentioned in the Introduction or Materials and Methods with their full name. No new abbreviations are introduced in the Results section.

TABULAR MATERIALS AND ILLUSTRATIONS

Tables and figures should complement, not duplicate, the text.

• Tables and illustrations are placed in the manuscript immediately after their first mention.
• Data are discussed after the table/figure, not before; each object is referenced only once — repeat references during data comparison are unnecessary.
• A figure title must not be part of the figure itself; it must appear below the figure and be formatted accordingly.
• Tables must be submitted in portrait orientation only, 14-point font.
• A single table must not exceed one printed page.

Text Sections

9. INTRODUCTION

Recommended section length: 1.5–2 pages of printed text (350–500 words). Statement of the problem in general terms, analysis of recent research and publications in which the solution of this problem was initiated and upon which the author relies, identification of previously unresolved aspects of the general problem. Must contain at least 7 references to literature from the past 6–8 years. It is not permissible to use more than 3 references in a row in the same brackets.

The section must contain essential information about the subject of the study and a concise justification of the material's relevance. All key concepts, abbreviations, and acronyms must be explained and defined in the Introduction. References are cited in square brackets in ascending order, separated by a comma and a space. Information in the Introduction must be consistent with the research results described in the Discussion.

10. PURPOSE

The purpose of the study is formulated as a separate item, corresponding to the title of the article and the content of the "Results" section. Contains a single sentence and cannot contain abbreviations.

11. MATERIALS AND METHODS

Recommended section length: 1.5–2 pages of printed text (250–500 words). The section may contain no more than 5 references.

This section must provide an opportunity for other researchers to replicate the experiments and confirm the author's results. If necessary, it may be divided into subsections. Compliance with ethical principles corresponding to the objects of the research must be indicated, in particular: the European Convention for the Protection of Vertebrate Animals, the Declaration of Helsinki, the principles of informed consent from the subjects, etc. (for more details, see the section "Publication Ethics and Its Violations"). In the final part of the section, if necessary, a subsection "Statistical Processing of Results" is provided, which describes the software and methods of analysing the obtained data.

12. RESULTS AND DISCUSSION

12.1 Results

Section length: 5–7 pages of printed text (1,250–1,750 words); references in the Results section are not permitted. Statistical results must be reported in both absolute and relative numbers. The section must include visualisation of the obtained data: tables, graphs, charts, figures, etc. The total number of visual and graphic elements must not exceed 6 units.

Data are presented very clearly in the form of brief descriptions with graphs, tables, and figures (do not duplicate information — use only one method of presentation). Graphs must have clearly labelled axis scales. When multiple curves are shown, their sequential numbers must be indicated directly on the figure. Figures other than charts should preferably be submitted in PCX format; photographs (no more than 4) — in JPEG.

Percentages must be presented in the article text or table together with the absolute value of the quantity taken as 100 %, for example 25 % of 120 patients. An alternative format is to state both the percentage and the absolute value simultaneously, for example: 25 % (30/120) or 30 of 120 patients (25 %).

When performing sequential percentage recalculations — i.e. calculating a percentage of a percentage (a percentage of the number of study objects in a subgroup previously described by percentage) — this procedure must be clearly described, and the numbers of study objects successively taken as 100 % must be presented.

12.2 DISCUSSION

Subsection length: 0.5–1 page, 6–8 references, placed after the Results. References to works by co-authors of the manuscript are permitted but must not exceed 2.

The subsection must contain a brief analysis of the statistical data obtained in the Results, as well as the conclusions drawn by the author based on processing these data — including the main mechanisms of structural and functional, physiological, and pathophysiological changes, features of therapeutic outcomes, the informative value of diagnostic methods, and a correlation of the obtained data with findings of researchers cited in the Introduction.

New and important aspects of the study findings must be highlighted; possible mechanisms or interpretations of the data must be analysed and, where possible, compared with data from other researchers. Information already stated in the Introduction and detailed data from the Results section must not be repeated. The Discussion may include evidence-based recommendations for clinical practice and possible applications of the findings in future research.

13. CONCLUSIONS

Section length: 0.5 pages; conclusions can be numbered. Conclusions must contain mandatory substantiation of statements using numerical or other data obtained during the study. In a few sentences, summarise the work completed: what was obtained, what it may indicate or mean, what purpose it serves and what possibilities it reveals. Reflect the prospects for further research. Avoid claiming priority and referring to completed work.

Review Articles

The journal publishes review articles on topical issues of medicine, based on a thorough analysis of the literature over the past 5 years. The structure of a review article is identical to that of an original study and includes the purpose, materials and methods, results and their discussion, and conclusions. The article must reveal the essence of the problem, its resolved and unresolved aspects. The use of colour schemes, figures, and graphs is important. Summaries and prospective solutions to the problem are mandatory elements.

The reference list must cite 30–50 sources published within the past 5 (five) years in journals indexed in Scopus/Web of Science databases, with an obligatory DOI index. Reference formatting requirements are identical to those for clinical and experimental articles, see link.

Review articles must include information on the literature search methods used across databases such as Scopus, Web of Science, MEDLINE, The Cochrane Library, EMBASE, Global Health, etc. The recommended length of a review article is 20–30 pages.

Clinical Case

This section contains articles on the latest international consensus statements on diagnosis and treatment, new international disease classifications, and clinical observations of rare diseases. Clinical observation articles are intended to familiarise practising specialists with rare diseases, including their features, clinical course, diagnosis, and treatment. The structure of clinical cases is identical to that of an original study and includes the purpose, materials and methods, results and their discussion, and conclusions.

Reference formatting requirements are identical to those for clinical and experimental articles, see link. The recommended length of a clinical case is 10–15 pages.
