Credible Mendelian Randomization Studies in the Presence of Selection Bias Using Control Exposures

open access: yesFrontiers in Genetics, 2021
Selection bias is increasingly acknowledged as a limitation of Mendelian randomization (MR). However, few methods exist to assess this issue. We focus on two plausible causal structures relevant to MR studies and illustrate the data-generating process ...
