 A causal diagram depicts the hypothesized causal processes that link two or more variables.\index{structural equation modeling!causal diagram}
 A common form of causal diagrams is the directed acyclic graph (DAG).\index{structural equation modeling!causal diagram}
 DAGs provide a helpful tool to communicate about causal questions and help identify how to avoid bias (i.e., over-estimation) in associations between variables due to confounding (i.e., common causes) [@Digitale2022].\index{structural equation modeling!causal diagram}
