Abstract

Case-control studies are a type of epidemiological study in which subjects are selected based on whether they have the outcome of interest, and then are examined for the presence of a prior exposure. By conditioning on outcome rather than exposure, case-control studies are very well suited to studies of rare outcomes, but are prone to selection bias in the identification of controls. Relative risks cannot be calculated from case-control studies, only odds ratios.
