Disease Measures, Study Designs 1. Which is a critical assumption of cumulative incidence A. Time is an intrinsic part of the denominator B. The entire population is followed for the entire period C. Time heals all wounds D. The population must not be at risk for the disease 2. Which is an advantage of true incidence rates over cumulative incidence measures? A. Incidence rates accumulate more time B. Incidence rates are closer to prevalence rates C. Incident rates do not need to meet the assumption that all individuals are followed for the entire observation period of the study D. Incidence rates are easier to calculate than cumulative incidence 3. Which study has a cross-sectional design? A. Participants are assessed at baseline and then again every 3 months for two years for occurrence of disease B. Patients who recovered from COVID-19 infection are matched and compared with patients who recovered from the seasonal flu for harmful lasting effects C. Patients are randomly selected to use one of 2 drugs for arthritis symptoms and followed over time to assess treatment response D. A random sample of auto mechanics is tested for lead poisoning 4.
