title: Putting risk in perspective: an evidence-based approach to selected risks associated with the use of oral contraception.
abstract: Although use of oral contraceptives is an effective way to prevent unintended pregnancy, concerns exist about associated adverse health outcomes. The concept of risk and different approaches to describing risk are discussed, and studies of health risks associated with specific exposures are used to illustrate the differences between relative and absolute risk. Evidence about health risks associated with use of oral contraceptives is presented within the context of population-based risk estimates.
