Following a long history of informal use in path analysis, causal diagrams (graphical causal models) saw an explosion of theor-etical development during the 1990s,1–3 including elaboration of connections to other methods for causal modelling. The latter connections are especially valuable for those familiar with some but not all methods, as certain background assumptions and sources of bias are more easily seen with certain models, whereas practical statistical procedures may be more easily derived under other models. We provide here a brief overview of graphical causal models,1–6 the sufficient-component cause (SCC) models of Rothman,7,8 Ch. 2 the potential-outcome (counterfactual) models now popular in statistics, health, and social sciences,9–15 and the structural-equations models long established in social sciences.11–14 We focus on special insights facilitated by each approach, translations among the approaches, and the level of detail specified by each approach.
