Specifically, we select a set of cases, or persons with the outcome of interest. 2. 2. 5- the nested case-control study: a specific type of case-control study that is usually designed from a cohort study, also used to assess new biomarkers (measures of biological processes) or to evaluate expensive tests or technologies.
