Cohort studies can be distinguished as either prospective or retrospective A prospective cohort study begins with the selection of two groups of non-diseased animals, one exposed to a factor postulated to cause a disease and the other unexposed. Subjects are then followed over time to measure one or more outcomes, such as the occurrence of disease.
