摘 要:
Mendelian randomization (MR) leverages genetic variants as instrumental variables (IVs) to estimate causal effects using observational data. In this talk, I will present some of our recent work on one-sample MR analysis. I will first introduce MR-SPLIT, a framework that mitigates bias from IV selection and weak instruments by separating instrument selection and effect estimation within a data-splitting scheme. I will then present MR-SPLIT+, an extension that identifies IVs that may violate the exclusion-restriction assumption due to genetic pleiotropy. Together, these approaches illustrate how instrumental variable methods can be adapted to enhance robustness and interpretability in modern MR applications.
