Summary
- What is new: Developed ‘MR.RGM’, a novel R-package that allows for constructing holistic causal networks in Mendelian randomization studies, overcoming the limitation of only considering pairwise exposure-outcome relationships.
- Why this is important: Traditional Mendelian randomization methods are limited as they consider only a pair of exposure and outcome at a time, failing to capture entire causal networks.
- What the research proposes: ‘MR.RGM’ uses a Bayesian reciprocal graphical model to construct causal networks with cyclic/reciprocal causation, enabling a comprehensive study of complex biological systems.
- Results: The ‘MR.RGM’ open-source R package enables exploring causal relationships among multiple variables in complex biological systems, advancing understanding of genetic networks and disease risks.
