Electure Question 2 A 10-year prospective cohort study on smoking and lung cancer was conducted. At baseline, the study included 3,000 smokers without lung cancer and 9,000 non-smokers without lung cancer. At the end of follow-up 130 of the smokers and 150 of the non-smokers had developed lung cancer. A. Assuming no deaths or other losses to follow up, calculate the 10-year cumulative incidence of lung cancer (per 1,000 population) in the overall study population. B. Calculate the appropriate measure of association between smoking and lung cancer in this population and interpret your results. C. What proportion of lung cancer occurrence in smokers is attributed to their smoking (assuming smoking is causally associated with lung cancer)? D. In what way might the measures in parts B and C be used by a public health practitioner?
