CASE CONTROL STUDY Meaning and
Definition
-
A case control study is a research design commonly used in epidemiology and medical research. It is an observational study that aims to evaluate the relationship between an outcome or disease and potential risk factors or exposures by comparing individuals or groups with the outcome of interest (cases) to those without (controls).
In a case control study, researchers select a group of individuals with the specific outcome or disease (cases) and a comparison group without the outcome (controls). Both groups are then assessed for their exposure to various risk factors or exposures retrospectively. The researchers collect detailed information on past exposures, behaviors, or characteristics through interviews, medical records, or questionnaires.
The purpose of a case control study is to determine whether a particular exposure or risk factor is associated with the outcome of interest. By comparing the likelihood of exposure between cases and controls, researchers can estimate the odds ratio, which represents the strength and direction of the association.
Case control studies are particularly useful when investigating rare outcomes or diseases, as they can efficiently assess the potential risk factors without the need for large sample sizes. However, they are prone to biases including selection bias and recall bias, which should be carefully considered and addressed to ensure accurate and reliable results.
