Epidemiology  1. True or False: A screening test with 99% specificity and 99% sensitivity will necessarily have higher predictive values than a screening test with 50% specificity and 50% sensitivity. 2. True or False: If it's found that participants in a screening program were much less likely to die from the disease screened for after 20 years of follow-up compared to non-participants, then the screening program must have been the reason for the reduced mortality.
