  "term": "Case control study",
  "field": "Chemistry",
  "definition": "An observational epidemiological study that compares a group of individuals with a specific disease or outcome, known as the cases, to a group of similar individuals without that disease, known as the controls. The study retrospectively examines the history of exposure to a suspected risk factor in both groups to determine if the exposure is associated with the outcome. The primary measure of association calculated from a case control study is the odds ratio, which quantifies the strength of the link between exposure and disease.",
