Publication Description
In the past 30 yr there has been an impressive increase in our ability to predict coronary heart disease (CHD). Some of the developments in epidemiology and statistics from which this derives are discussed. While it is not possible to specify a useful upper bound to the predictability of coronary heart disease, the paper provides guides to determining the effectiveness of various CHD risk functions, with illustrative examples from the Framingham Study, and discusses interpretative problems.
