This session will introduce participants to the field of causal inference. We will review the distinction between causal and predictive research questions, and where machine learning and traditional epidemiological techniques may be misinterpreted. We will review the fundamentals of directed acyclic graphs (DAGs), and how they can be used to determine appropriate sets of variables for estimating total causal effects of exposure (treatment). The session will highlight when automated “sophisticated analyses” will likely fail, and why clinician expertise is required to make sense of any data that will be used in the development of interventions.
