Presentation of research results in the form of an article, dissertation or conference abstracts is as important stage of the project as the others. Incorrectly presented research results can devaluate the importance and significance of even the most methodologically well-designed and well-conducted research. This paper reviews the most common mistakes made by researchers at the stage of publishing the results of medical research. The article presents errors related to incomplete or redundant description of statistical methods, incorrect selection of statistical parameters for describing medical data, their erroneous interpretation, as well as defects in the application of statistical criteria. In addition, errors made in the graphical representation of research results are affected. The material presented in the article does not claim to be an exhaustive list of possible mistakes that can be made when presenting research results. This material is a summary of the authors' experience in reviewing scientific manuscripts and publications. Taking into account the experience described in this article will allow for better presentation of the results of implemented medical research in theses, articles and conference materials.
