title: Clinical studies' assessment.
abstract: The paper gives some more general remarks on clinical studies from the perspective of a biometrician. Prospective randomised clinical trials are the study type with highest evidence. But there are other study types, too, which have their legitimacy in the process of medical knowledge finding and quality assurance. It is important to use each type in the right place and in the right way. Analysis and interpretation have to take care for the study type.
