title: Epidemiology in the courtroom: an evidence-based paradigm for the determination of causation in compensation environments.
abstract: OBJECTIVE
  Identify an evidence-based paradigm for the determination of causation of occupational injury and illness litigation.
  
  
  METHODS
  The Westlaw and LexisNexis databases were used to identify legal principles governing the admissibility of scientific evidence in legal proceedings. The Medline database was referenced to identify evidence-based methods for the determination of causation complying with legal precepts for the admissibility of scientific testimony.
  
  
  RESULTS
  Expert witness testimony must be relevant and reliable. Testimony must be sufficiently based on reliable facts and data. Testimony must be the product of reliable principles or methods. The witness must have reliably applied the principles and methods to the facts of the case.
  
  
  CONCLUSIONS
  Conscientious application of the National Institute for Occupational Safety and Health Guide for the Determination of Work-Relatedness of Disease, as adapted, comforts with legal prerequisites for the admissibility of scientific evidence in medicolegal proceedings.
