Use the chart and information below to answer the following fivepart question. The chart below shows the followup experience of a cohort followed from time zero for ten years. Note that the first ten persons in the chart are exposed and the second ten persons in the chart are unexposed. Assume that all events occur at the end of a year. For example, person 1 was lost to followup at the end of year 9, so this individual accumulated 9 personyears of followup. Part I: Prevalence of disease What is the prevalence of disease in the total cohort in the middle of year 6? Answer as a percentage and round to the nearest tenth of a percent (e.g. 6.78% becomes 6.8%) Answer _________% Part II: Simple cumulative incidence of disease What is the simple cumulative incidence among the exposed? Answer as the number of cases per 1,000 people over 10 years. cases per 1,000 people over 10 years. Part III: Simple cumulative incidence of disease What is the simple cumulative incidence among the unexposed? Answer as the number of cases per 1,000 people over 10 years. cases per 1,000 people over 10 years. Part IV: Incidence rate of disease What is the incidence rate of disease among the exposed? Answer as the number of cases per 1,000 personyears. cases per 1,000 personyears. Part V: Incidence rate of disease What is the incidence rate of disease among the unexposed? Answer as the number of cases per 1,000 personyears. cases per 1,000 personyears
