Identifying and adjusting for confounders is challenging and various methods have been proposed. Directed acyclic graphs (DAGs) are a causal inference tool, being simultaneously qualitative and quantitative. They offer us a representation of the relationship between variables and support the selection of confounders to consider. In this talk, main issues with previous approaches will be presented, followed by an overview of DAGs, alongside with its main applications and developments.engDirected Acyclic GraphsExposure on DiseaseGrafos Acíclicos DirigidosDeterminantes da Saúde e da DoençaEpidemiologiaconference object
