Epidemiology and the law: courts and confidence intervals.

Abstract

Beginning with the swine flu litigation of the early 1980s, epidemiological evidence has played an increasingly prominent role in helping the nation's courts deal with alleged causal connections between plaintiffs' diseases or other harm and exposure to specific noxious agents (such as asbestos, toxic waste, radiation, and pharmaceuticals). Judicial reliance on epidemiology has high-lighted the contrast between the nature of scientific proof and of legal proof. Epidemiologists need to recognize and understand the growing involvement of their profession in complex tort litigation.
