case-control studyA type of epidemiological study that compares subjects who have a disease or condition (the cases) with similar subjects who do not have the disease or condition (the controls). In a case-control study the medical and lifestyle histories of the subjects in each group are investigated to learn what factors may be associated with the disease or condi [..]

case-control studyA study designed to determine the association between an exposure and outcome in which patients are sampled by outcome. Those with the outcome (cases) are compared to those without the outcome (controls) with respect to exposure to the suspected harmful agent.

case-control studyA form of association study in which “case” individuals with, for example, a disease are compared with “control” individuals without it.

case-control studyThe observational epidemiologic study of persons with the disease (or other outcome variable) of interest and a suitable control (comparison, reference) group of persons without the disease. The relationship of an attribute to the disease is examined by comparing the diseased and nondiseased with regard to how frequently the attribute is present or [..]

case-control studyA research study that compares one group of people with a particular disease to a very similar group that does not have the same disease.

case-control studyA study which involves identifying patients who have the outcome of interest (cases) and patients without the same outcome (controls), and looking back to see if they had the exposure of interest.

case-control studyA study that starts with identification of people with the disease, disorder or condition of interest (the cases) and a suitable control group without the disease or outcome (the controls). The relationship of an attribute (medicine, treatment, exposure or risk factor) to the outcome of interest is examined by comparing the frequency or level of th [..]

case-control studyA systematic comparison of troublesome persons, places, times, or events to untroublesome ones to find out the characteristics that might cause the problem. This type of study is particularly useful when troublesome cases are a very small proportion of all cases.

case-control studyis one of the three basic analytical observational study designs. A case-control study starts by defining groups according to the outcome (e.g. disease present or absent) and then looks back to establish the study factor (e.g. exposure present or absent). A case-control study has a backward directionality. A case-control study is unable to estimate [..]

case-control studytypically examines multiple exposures in relation to a disease; subjects are defined as cases and controls, and exposure histories are compared (Aschengrau & Seage, 2007, p. 137).
