DAGitty: a graphical tool for analyzing causal diagrams
Causal diagrams, also known as directed acyclic graphs, 1, 2 provide an entirely graphical,
yet mathematically rigorous methodology for minimizing bias in epidemiologic studies. 3, 4
The analysis of causal diagrams can be cumbersome in practice, and lends itself well to
automatization by a computer program. Important first steps in this regard include the
development of the DAG program by Knüppel and Stang 5 and dagR by Breitling. 6 We
announce the release of DAGitty, which provides a graphical user interface tailored to draw …
