nested case-control study
- nested case-control study
- a case-control study nested within a cohort study: a population is identified and baseline data obtained and stored; after following the cohort for some time, a case-control study is performed using the small percentage of people who develop the disease, with controls selected as a sample of those surviving members without disease who were at risk at the time of occurrence of each case. Baseline data can be analyzed solely for this small subset of the original population, and recall bias and other hazards of case-control studies are avoided.
