Dr. Samet gave an excellent presentation on the strength of evidence to be used in determining causal relationships. The importantace of Surgeon General’s 1964 Report was discussed but why was no mention made of of the controlling statutory requirement passed by the Congress in 2000—the Data Quality Act?
Strength of Evidence
Dr. Samet focused on some of what are usually referred to as the “Hill criteria” (or factors) or “criteria for causality” for evaluating epidemiologic studies. However, a key omission was that he did not discuss the matter of evaluating the QUALITY of a study in weighting the evidence. This is where the Informaiton Quality Act and its standards apparently comes in.
