Materials 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.
Results
Results should be clear and concise. SI units should be used.
Discussion
That section should extend, not repeat, the importance of the study results. It is often appropriate combine Results and Discussion. Extensive quotations and published literature analyses should be avoided in this section.
Conclusion
The main conclusions of the study may be presented in a this section. It may stand alone or form a subsection of a Discussion or Results sections.

Title page – necessary information

The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

An should be so designed that it can be presented separately. Avoid references, but if essential, then cite the author(s) and year(s). Non-standard or uncommon abbreviations can be used, but must be defined at their first mention.
For original articles only, it is necessary for the abstract to be divided into five sections:
Introduction, Aim, Materials and methods, Results, Conclusion
Data stated in the abstract must also occur in the text and tables.


Key words
Five keywords or short phrases in Polish and English should be placed at the bottom of the title page. It is suggested that terms according to Index Medicus (Medical Subject Headings) should be used. Key words may not be a repetition of the title
