* NOTE: In the case of the co-existence of several authors of a manuscript (this applies to all types of articles such as overviews, original works, case descriptions, etc.), the contribution of individual authors to the creation of the work (with information regarding who the author is of the concept, assumptions, utlilized method, who conducted the research, data analysis, wrote the manuscript, etc.) should be stated.
All cases of scientific misconduct, including the so-called phenomenon "Ghostwriting" and "guest authorship" will be exposed, including notifying the relevant authorities (institutions employing the authors, societies, associations, scientific editors, etc.).
The phenomenon of "ghostwriting" is understood as when someone has made a substantial contribution to the work, but his/her participation has not been disclosed as one of the authors or stated in the acknowledgements. "Guest authorship" is understood as a situation in which an author's participation is minimal or even non-existent, and yet he/she is stated as the author/co-author of the publication.
The editors are required to document any form of scientific misconduct, especially concerning violations and breaches of rules of ethics in force in science. Abstract (in Polish and English). It should contain no more than 250 words and it should be divided into four sections entitled: Introduction, Materials and Methods, Results, and Conclusions.
Key words (in Polish and English). 3 to 10 key words or key phrases should be placed under the abstract (in Polish and English, respectively), corresponding as much as possible to the Medicus Medical Subject Headings Index.
Text. Original papers should be divided into the following sections: Introduction, Materials and Methods, Results, Discussion, Conclusions. Review articles should be divided differently. Manuscripts should not exceed the following sizes: original paper – 3000 words, review paper – 6000 words, case description – 2000 words, letter – 1000 words. The given word limits exclude the abstract, tables and references. Tables and figures should be pasted in the appropriate places within the text.
The employed statistical methods should be described in sufficient detail so that a reader with access to the source data and statistical knowledge should able to verify the reported results. Wherever possible, use quantitative descriptions with appropriate measurements of error or uncertainty (such as confidence intervals). Avoid relying solely on the level of probability (p-value) calculated during statistical hypothesis testing, which omits vital information about the scale of the observed effect.
References. Should be arranged according to the order they appear in the text.
Journals. Citations should include: position number, authors’ surnames and initials (if there are no more than 7 authors, all the names should be given, otherwise only three of them followed by “et al.”), paper title, journal title (journal title abbreviations according to Medicus Index ), year, volume (Arabic numerals), number of first and last page. Do not use statements: ”in press”, ”in preparation”, ”oral information” – in substantiated cases, such statements can be placed in appropriate places in the text.
