The annual incidence of coronary heart disease (CHD) among smokers (exposed) in the fictional country of Winterfell is 24.0 per 10,000 per year. The annual incidence of CHD among nonsmokers (unexposed) in Winterfell is 6.0 per 10,000 per year. The proportion of smokers in Winterfell is 14%
Based on the above data, calculate the proportion of incident CHD in the total population in
Winterfell that is attributable to smoking (i.e., Population Attributable Risk Percent or PAR%).
Show your work, and report your answer rounded to the tenths decimal place (i.e., answer to the
nearest 0.1%).
