- A case-cohort study is similar to a nested case-control study in that the cases and non-cases are within a parent cohort; cases and non-cases are identified at time [math]\displaystyle{ t_1 }[/math], after baseline. In a case-cohort study, the cohort members were assessed for risk factors at any time prior to [math]\displaystyle{ t_1 }[/math]. Non-cases are randomly selected from the parent cohort, forming a subcohort. No matching is performed.
