WebASSUMPTIONS A single study may present multiple opportunities to bound the same average causal effect under slightly different identifiability assumptions. For example, in Mendelian random-ization (MR), researchers often propose multiple genetic variants as instruments to estimate the same exposure–outcome relation. WebUnder the standard identifiability assumptions, namely Assumptions 1–4 and separate assumptions on the missingness mechanism as described in the previous section, multiple imputation can be an adequate strategy to address the challenge of generalizing the average treatment effect with incomplete covariates.

This difference is a fundamentally unobservable quantity. For any individual, we can only ever observe their blood pressure either in the situation (1) when they take the drug or (2) when they don’t.
