title: The relationship of relative risk and positive predictive value in 2 X 2 tables.
abstract: Both relative risk and positive predictive value are used to assess the relationship between an attribute and a disease state. While they can be equated only in one uninteresting situation, they do have an explicit algebraic relationship which is demonstrated in this paper. This relationship may provide an interesting link between epidemiology and medical decision analysis.
