For Episode 5, we invited Louise Poppe to introduce us to causal models, with a particular focus on Directed Acyclic Graphs (DAGs). Together, we discuss why researchers in epidemiology β and, in fact, across many scientific disciplines β can benefit from integrating DAGs into their study workflow. We talk about how to get started with causal thinking, common pitfalls and challenges when building DAGs, and what insights these models can provide for study design, analysis, and interpretation.
This episode offers an accessible introduction to causal thinking with DAGs and is a great opportunity to expand your methodological research toolbox.
