• the need to notify an individual, the guardian of this person or another person empowered to act on behalf of this person, about the intention to create a photo, video recording, any other image in an identifiable form, and about the purpose of these actions. Each such person must give the author explicit written consent for the author to perform such actions, which must remain with the author and, if necessary, if requested by the editors, provide a copy of such consent. When research involves children, special attention must be paid to obtaining consent. In a situation where the child's parents or guardians do not agree that the child's image will be used, consent is not considered obtained;
• the need to ensure that parts that allow identifying a person are not visible in the image, or that references are made to the person's name/surname or other personal data in the text. Image captions must be respectful;
• the need to ensure that the manuscript does not use hospital/social security numbers, as well as personal information such as dates of birth, names/initials of research subjects;
• the need to ensure that images of research subjects are not used in the manuscript, even if consent was obtained, but the image itself does not carry informational load in the context of obtaining scientific results. The deliberate changes in the identification parameters of research subjects allowed in order to protect anonymity imply obligatory guarantees of the authors regarding the invariability of the scientific meaning. For the purposes of anonymity, when no consent has been obtained, it is not enough to use blurring of the face or applying a black stripe over the eyes for photographs. Consensus at the level of formalization is not necessary if the images themselves are completely anonymous: X-rays, ultrasound images, pathology slides or laparoscopic images. Moreover, such images should not contain any identification marks and text that will allow the identification of the subject.

If the manuscript reports on the conducted clinical trials, it is mandatory to indicate that these clinical trials were registered before the registration of patients, and information about this can be stored in a public storage, unless the main purpose of the trials was to study pharmacokinetics.

If desired, the authors can submit to the editorial office additional materials confirming the results obtained in the course of the study. These can be video or audio files, screenshots or printouts of the results of using (displaying) software products, Excel files, etc.
