What Is Epidemiology?

Epidemiology

In the product liability context, epidemiology refers to the study of the incidence, distribution, and etiology of disease or harm in human populations. Epidemiological studies include a variety of different study designs, such as prospective and retrospective cohort studies, case-control studies, randomized controlled trials, and meta-analysis. Epidemiology is a critical, and sometimes mandatory, element for establishing general causation.
