Associations of 35 Serum and Urine Biomarkers With Vascular Dementia—A Mendelian Randomization Study [PDF]

Brain and Behavior
Background The relationship between serum and urine biomarkers with vascular dementia (VD) has been increasingly highlighted by observational studies. Yet, the causal nature underlying these associations remains elusive.

Mendelian randomization and type 2 diabetes [PDF]

Cardiovascular Drugs and Therapy, 2016
Type 2 diabetes (T2DM) is a common, complex disease that poses a substantial burden on individual and population health, but we have relatively limited understanding of its underlying pathophysiology.

Mendelian randomization

Nature Reviews Methods Primers, 2022
Mendelian randomization (MR) is a term that applies to the use of genetic variation to address causal questions about how modifiable exposures influence different outcomes. The principles of MR are based on Mendel's laws of inheritance and instrumental variable estimation methods, which enable the inference of causal effects in the presence of ...

Pleiotropy-robust Mendelian randomization [PDF]

International Journal of Epidemiology, 2016
AbstractBackgroundThe potential of Mendelian Randomization studies is rapidly expanding due to (i) the growing power of GWAS meta-analyses to detect genetic variants associated with several exposures, and (ii) the increasing availability of these genetic variants in large-scale surveys.

Causal relationship between obesity and iron deficiency anemia: a two-sample Mendelian randomization study

Frontiers in Public Health, 2023
BackgroundObservational studies have suggested an association between obesity and iron deficiency anemia, but such studies are susceptible to reverse causation and residual confounding.

Mendelian Randomization: Concepts and Scope [PDF]

Cold Spring Harbor Perspectives in Medicine, 2021
Mendelian randomization (MR) is a method of studying the causal effects of modifiable exposures (i.e., potential risk factors) on health, social, and economic outcomes using genetic variants associated with the specific exposures of interest. MR provides a more robust understanding of the influence of these exposures on outcomes because germline ...

Genome-wide and Mendelian randomisation studies of liver MRI yield insights into the pathogenesis of steatohepatitis [PDF]

, 2020
Background A non-invasive method to grade the severity of steatohepatitis and liver fibrosis is magnetic resonance imaging (MRI) based corrected T1 (cT1).

Mendelian Randomization [PDF]

JAMA, 2009
Despite several observational studies showing that lipoprotein(a), or Lp(a), is associated with myocardial infarction (MI)1, 2, only circumstantial evidence exists regarding the causal nature of this association. Observational epidemiological studies, even with a sound prospective design, can provide hints to disease pathogenesis when the effect size ...
