Directed Acyclic Graphs (DAGs) are a useful tool to visualize the assumed relationship between variables. By mapping variables and visualizing causal structures, DAGs are particularly helpful to researchers who aim to explore the effectiveness of treatments on health outcomes, as DAGs help identify the role of covariates that need to be taken into account in the analysis, along with the treatment…
