Overview of Mendelian Randomization Analysis

open access: yesJournal of Rheumatic Diseases, 2020
The inference of causality from observational evidence may be problematic, as observational studies frequently include confounding factors or reverse causation for the identification of associations between exposure and outcome. Thus, in observational studies, the association between a risk factor and a disease of interest may not be causal.

Causal effects of gut microbiome on hypertension: a Mendelian randomization study

open access: yesFrontiers in Microbiology, 2023
BackgroundPrevious observational studies have shown that there is an important relationship between gut microbiota and hypertension, we performed a two-sample Mendelian randomization analysis to examine whether the gut microbiota is causally related to ...

The role of smoking and alcohol in mediating the effect of gastroesophageal reflux disease on lung cancer: A Mendelian randomization study

open access: yesFrontiers in Genetics, 2023
Observational studies have suggested a positive association between gastroesophageal reflux disease and lung cancer, but due to the existence of confounders, it remains undetermined whether gastroesophageal reflux disease (GERD) has a causal association ...

Causal relationship between air pollution, lung function, gastroesophageal reflux disease, and non-alcoholic fatty liver disease: univariate and multivariate Mendelian randomization study

open access: yesFrontiers in Public Health
BackgroundThe association between air pollution, lung function, gastroesophageal reflux disease, and Non-alcoholic fatty liver disease (NAFLD) remains inconclusive. Previous studies were not convincing due to confounding factors and reverse causality. We

Glucosamine supplementation contributes to reducing the risk of type 2 diabetes: Evidence from Mendelian randomization combined with a meta-analysis

open access: yesJournal of International Medical Research
Objective Observational studies on glucosamine supplementation and type 2 diabetes risk have shown inconsistent results, necessitating the use of Mendelian randomization to clarify the true causal relationship.

Stratification by Smoking Status Reveals an Association of CHRNA5-A3-B4 Genotype with Body Mass Index in Never Smokers [PDF]

open access: yes, 2014
We previously used a single nucleotide polymorphism (SNP) in the CHRNA5-A3-B4 gene cluster associated with heaviness of smoking within smokers to confirm the causal effect of smoking in reducing body mass index (BMI) in a Mendelian randomisation analysis.

Rheumatoid arthritis and risk of lung diseases in East Asians and Europeans: Evidence from a Mendelian randomization study

open access: yesSAGE Open Medicine
Background: Rheumatoid arthritis might increase the risk of lung diseases, such as interstitial lung disease and lung cancer. However, the causal relationships remained unclear.

Diabetes and Risk of Arterial Stiffness: A Mendelian Randomization Analysis [PDF]

open access: yesDiabetes, 2016
We aimed to explore the causal association between type 2 diabetes (T2D) and increased arterial stiffness. We performed a Mendelian randomization (MR) analysis in 11,385 participants from a well-defined community study in Shanghai during 2011–2013. We genotyped 34 T2D-associated common variants identified in East Asians and created a genetic risk score
