The attributable risk is the rate of occurrence of disease in exposed individuals as caused by that factor.

For example, if a patient smokes no cigarettes and the annual death rate is 0.07, the attributable risk is (definitely) zero. An individual smoking between 1 and 14 cigarettes is in a population with an annual death rate of 0.57; thus an attributable risk of 0.5.
