title: [Role of statisticians in epidemiological research].
abstract: The relevance of statistical methods for epidemiological research in rheumatology is under discussion. Different from randomized clinical studies in observational studies, the danger of a systematic bias always exists due to prognostic differences between the groups that are to be compared. A special professional competence in statistics is indispensable in order to handle this adequately, to apply suitable methods and to develop methods anew to achieve clinically relevant results. This is made clear with the help of various studies from a statistician's field of work.
