Case Control Study 2
Case Control Study 2 : A study which starts with the identification 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 non-diseased with regard to how frequently the attribute is present or, if quantitative, the levels of the attribute, in the two groups. Syn: Case Comparison Study, Case History Study, Case Referent Study, Retrospective Study
