16. In a study concerned with the possible effects of air pollution on the development of chronic bronchitis, the following data were obtained.  A sample population of 8,524 men who lived in a city with high levels of air pollution was examined in January 2012.  At the initial visit for the study, 352 men were found to have chronic bronchitis and were excluded from further study.  The bronchitis-free men in the study were followed for 5 years, and 618 new cases of chronic bronchitis occurred during that time.  The men who were followed during the study contributed 28,947 years of person-time.   What is the cumulative incidence of chronic bronchitis over the 5-year study, expressed as a percentage?  Round to the nearest whole number.  Include only the numerical answer (no units) in the answer box.

QUESTION 1 Match each description to the correct study design. Study designs may be used more than once. ◆ Incidence data is not available with this study design, so an odds ratio is an appropriate measure of association to calculate. ◆ This study design allows for the evaluation of multiple outcomes. ◆ The temporal sequence between the exposure and outcome is clear for this study design; therefore, incidence data is available and a risk ratio can be calculated. ◆ With this study design, exposure status is assessed, and then participants are followed up over time to see who develops the outcome. ◆ Recall bias is a common issue with this study design because exposure information is collected from the past. QUESTION 2 A. Cohort study B. Case-control study Consider the following scenario for the questions that follow. In a recent case-control study, investigators enrolled 300 adults with heart disease and 300 healthy adults. During interviews with the participants, the investigators…
