Attributable risk (AR) describes the risk for developing the disease or outcome under study that can be attributed to the exposure as compared with the risk that exists without exposure.
AR is calculated as the difference between disease or outcome incidence among those with the exposure and those without the exposure.
In this scenario the incidence
rates of death from lung cancer are already computed, thus AR is equal to the difference in the death rate among smokers compared to that among nonsmokers, or AR = 2.27 - 0.07 deaths per
1000 persons.
