Watch Video

Speakers: Jo Taylor, PhD, is a CDC Epidemic Intelligence Service fellow based at the Minnesota Department of Health.


About the presentation: Case-case comparison can be a useful tool in public health, especially for hypothesis generation to identify novel risk factors for a poorly understood disease, or when resources are limited to recruit controls. This webinar will provide an overview of case-case comparisons, the applications in public health and the benefits and limitations of this approach. As an example, a recent case-case comparison that was used to explore a wide range of potential unknown risk factors for community-associated Clostridioides difficile infection in Minnesota will also be described.

By the end of the presentation, participants will be able to:
  • Describe applications of case-case comparisons in public health
  • Understand the strengths and limitations of case-case comparison methods
  • Apply appropriate selection of case groups depending on data available
