"The circle of life: epidemiologic methods for dealing with treatment-confounder feedback"
"In epidemiology, many (if not most) of the exposures of interest occur more than once during an individual’s life. These sustained or recurring exposures are more complicated to analyze because the reasons for exposure or non-exposure may change over time, and even worse, may be affected themselves by prior exposure patterns—i.e. treatment-confounder feedback. This feedback can create bias in our attempts to understand causal effects even in randomized clinical trials. In this talk, I will describe the problem that can arise when attempting to use traditional methods, how to think through whether this source of bias may be occurring in your study design using directed acyclic graphs (DAGs), and explain modern causal inference techniques for minimizing treatment-confounder feedback in epidemiologic research including inverse probability weighting and the parametric g-formula."
