The definition of medical research is as follows: Medical research is research which aims to answer a question in the area of disease and health (aetiology, pathogenesis, symptoms, diagnosis, prevention, outcome or treatment of disease) by systematically gathering and studying data. The research aims to contribute to medical knowledge which is also valid for populations outside the direct research population. (Memo from the Central Committee on Research Involving Human Subjects, Definition of medical research, 2005, ccmo.nl)
