- In this fictitious example of a cohort study, we found that in a factory of 3,000 workers, 1,000 workers were exposed to toxic substances, and 2,000 were not. During the study period, 800 of the exposed workers developed some type of lung disease, and only 40 of the non-exposed workers developed a lung disease. A. What is the incidence of lung disease among exposed workers? Use 1,000 as the multiplication factor and answer should be in whole numbers. B.
