  • Examining the effect of an exposure on the development of some outcome (correct)
  • Assessing the efficiency of time and money in research

    • In a case-control study, what is compared to controls?

  • Exposures observed by investigators
  • Cases (those with a specific outcome) (correct)
  • Non-exposed subjects
  • Incidence rates of outcomes or diseases

    • What is one of the advantages of case-control studies?

  • Minimizes observation and selection bias
  • Provides incidence rates
  • Ideal for rare outcomes or disease (example: pancreatic cancer) (correct)
  • Efficient use of time and money because it avoids waiting for the outcome/disease to develop
