According to the Regulation of the Minister of Health and Social Affairs of 11 May 1999 establishing detailed rules regarding the appointment, funding and mode of operation of bioethics committees, only medical experiments are subject to ethics evaluation in Poland. Because this study was not an experiment, I did not seek approval. Additionally, as no participants were involved in the study, the consent of participants was not applicable in this case.
