Clinical research can generally be divided into four broad objectives based on the intended use of the information obtained by the study: diagnosis, prognosis, treatment effects, and aetiology. Each of these research objectives is associated with a different definition. Table 1⇓ gives examples of how these four definitions of risk factor are used in the scientific literature and shows how each definition describes a different relation between the dependent variable and the independent variable. View this table: Table 1 Objectives of clinical research and associated definitions of risk factor A variable may qualify as a risk factor under more than one definition of the term.
