Summary
This 2023 educational review introduces nephrologists to Mendelian randomisation as a causal inference tool, explaining core MR principles and the application of different MR designs in kidney disease research. The authors address methodological considerations specific to nephrology, including potential biases and limitations of genetic epidemiological approaches. The paper appears designed to bridge advances in causal inference methodology and clinical nephrology practice, making statistical genetics methods more accessible to clinicians without extensive training in genetic epidemiology.
Regional applicability
As a methodological review focused on causal inference techniques in kidney disease research, the principles and guidance are broadly applicable across healthcare systems. The applicability to United Kingdom nephrology research and practice depends on the uptake of Mendelian randomisation methods in UK renal epidemiology and clinical research; the paper itself does not address UK-specific policy or clinical contexts.
Key measures
Not applicable — methodological review rather than empirical study
Outcomes reported
This educational review synthesises Mendelian randomisation (MR) principles and discusses the strengths, limitations, and methodological considerations of different MR designs for causal inference in kidney disease research.
