attributable fraction

The percentage of instances of an illness that can be accounted for by a particular risk factor. For example, people exposed to asbestos have a certain risk of developing lung cancer, and if they also smoke tobacco, they are also at risk from that factor. These risks may be estimated from cohort studies.
Synonym: additional risk; attributable risk
