MR Dictionary

Pleiotropy-robust MR estimates the causal effect in the presence of pleiotropy by identifying a patient subgroup for which the genetic variant does not affect the exposure. The pleiotropic effect estimated from this subgroup is then subtracted as an offset from the TSLS estimate. 

Requires a perfect `no-relevance subgroup’. The pleiotropic effect must be constant across covariate subgroups.
