In this episode, we speak with researcher and physician Dr. James Diao about when and why race should be included or excluded from clinical algorithms. We focus on his work evaluating the implications of including race as a variable in two clinical algorithms: one used to assess lung function, and another used to assess cardiovascular disease risk.
