Causal mediation analysis with multiple causally non-ordered mediators [PDF]
Statistical Methods in Medical Research, 2015 In many health studies, researchers are interested in estimating the treatment effects on the outcome around and through an intermediate variable. Such causal mediation analyses aim to understand the mechanisms that explain the treatment effect. Although multiple mediators are often involved in real studies, most of the literature considered mediation ...

Semiparametric Estimation for Causal Mediation Analysis with Multiple Causally Ordered Mediators [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2021 AbstractCausal mediation analysis concerns the pathways through which a treatment affects an outcome. While most of the mediation literature focuses on settings with a single mediator, a flourishing line of research has examined settings involving multiple mediators, under which path-specific effects (PSEs) are often of interest. We consider estimation

Causal Mediation Analysis for Stochastic Interventions [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2020 SummaryMediation analysis in causal inference has traditionally focused on binary exposures and deterministic interventions, and a decomposition of the average treatment effect in terms of direct and indirect effects. We present an analogous decomposition of the population intervention effect, defined through stochastic interventions on the exposure ...

Investigating potential mediator between statin and coronary artery calcification. [PDF]
PLoS ONE, 2018 Statins are mainstay anti-lipidaemic treatments for preventing cardiovascular diseases but also known to increase coronary artery calcification (CAC). However, underlying relationship between statin and CAC is still unclear.

Continuous‐time causal mediation analysis
Statistics in Medicine, 2019 While causal mediation analysis has seen considerable recent development for a single measured mediator (M) and final outcome (Y), less attention has been given to repeatedly measured M and Y. Previous methods have typically involved discrete‐time models that limit inference to the particular measurement times used and do not recognize the continuous ...

Causal Mediation Analysis [PDF]
, 2019 Estimating the mechanisms that connect explanatory variables with the explained variable, also known as "mediation analysis," is central to a variety of social-science fields, especially psychology, and increasingly to fields like epidemiology,.

A general approach to causal mediation analysis. [PDF]
Psychological Methods, 2010 Traditionally in the social sciences, causal mediation analysis has been formulated, understood, and implemented within the framework of linear structural equation models. We argue and demonstrate that this is problematic for 3 reasons: the lack of a general definition of causal mediation effects independent of a particular statistical model, the ...
