Summary
Au Yeung and Gill (2023) develop standardised reporting guidelines for Mendelian randomisation studies, a causal inference method increasingly applied in nutritional epidemiology and biomedical research. The guidelines formalise consistent reporting practices to enhance transparency and reproducibility across MR investigations. This methodological contribution supports strengthening evidence synthesis and comparability in observational and genetic epidemiology, particularly relevant where MR is used to evaluate dietary and nutritional exposures.
Regional applicability
These reporting standards are internationally applicable and would support UK-based researchers and funders (including NIHR, MRC) in evaluating the quality and comparability of MR studies, particularly those investigating dietary and nutritional risk factors. Adoption of these guidelines would strengthen the evidence base for UK nutrition and health policy development.
Key measures
Reporting standards and checklist items for Mendelian randomisation study design, conduct, and interpretation
Outcomes reported
The study establishes and formalises standardised reporting guidelines for Mendelian randomisation (MR) studies, a genetic epidemiological method used to infer causality. The guidelines aim to promote transparency, reproducibility, and methodological consistency in MR investigations.
