Researchers have developed a new statistical method for inferring causal path-specific effects in longitudinal studies, particularly when dealing with repeated treatments and multiple mediators. The approach, detailed in a paper and implemented in the R package flexPaths, uses semiparametric inference and relies on assumptions like consistency and positivity. The method allows for variations in the number, type, and order of intermediate variables across treatment occasions. Simulations demonstrate the finite-sample performance and robustness of the estimators, and the approach has been applied to analyze the effects of sustained smoking on blood pressure through body mass index in the Framingham Heart Study.
