Summary

This guideline paper from a collaborative group of epidemiologists and geneticists establishes best-practice standards for designing, conducting, and reporting Mendelian randomization investigations—a statistical method for inferring causal relationships from genetic data. The guidelines span nine essential sections from study conception through interpretation, and are designed to support both practitioners and peer reviewers. The authors commit to periodic updates reflecting community feedback and methodological advances.

UK applicability

These guidelines are internationally applicable and would support UK-based researchers undertaking Mendelian randomization analyses in nutritional epidemiology and food systems research. They establish transparent standards that align with UK journal editorial and funding body expectations.

Key measures

Framework domains including genetic variant selection criteria, harmonisation procedures, robustness of causal inference methods, and interpretation standards

Outcomes reported

The paper provides comprehensive methodological guidelines across nine domains: motivation, data sources, genetic variant selection, harmonisation, primary analysis, sensitivity analyses, data presentation, and interpretation of findings. It establishes standards for practitioners, journal editors, and reviewers assessing Mendelian randomization investigations.
