Nested Case Control Study

Case control study design has many benefits however it may be a less tedious process when used in conjunction with an ongoing cohort study. For instance a study on the levels of HDl cholesterol associated with cardiovascular disease would yield the results in the form of an odds-ratio only when using a case-control study.

    In a case-control study, two populations are compared, for instance,in a cardiovascular clinic: patients with a cardiovascular event and patients without a cardiovascular event (as diagnosed by the attending physician and the consultant cardiologist). 
     However if one wants to determine that association within one population it is more economical and TIME SAVING to use the data collected from a cohort study. Thus first collecting alll the patient information for example blood pressure and lipid profile, it would be wise to collect the information leading to a cohort of patients.
