Abstract:
:A major objective of epidemiologic investigation is to determine whether or not an association between an exposure and a condition exists in a human population. The presence of such an association cna be explored using three distinct strategies, the cohort, the case-control, and the cross-sectional approaches. This paper describes each of these research designs and discusses their advantages and disadvantages.
