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 ...

Inference for Instrumental Variables: A Randomization Inference Approach
The method of instrumental variables (IV) provides a framework to study causal effects in both randomized experiments with noncompliance and in observational studies where natural circumstances produce as-if random nudges to accept treatment ...

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

‘Mendelian randomization’ equals instrumental variable analysis with genetic instruments [PDF]
AbstractInterest in instrumental variable (IV) analyses using genetic instruments has been growing over the past 4 years. The background, strength and weaknesses of this approach, which in the epidemiology literature has been referred to as ‘Mendelian randomization’, has been recently reviewed by Lawlor et al. (Statist. Med. 2007. DOI: 10.1002/sim.3034)

Genetically Determined Plasma Lipid Levels and Risk of Diabetic Retinopathy: A Mendelian Randomization Study. [PDF]
Results from observational studies examining dyslipidemia as a risk factor for diabetic retinopathy (DR) have been inconsistent. We evaluated the causal relationship between plasma lipids and DR using a Mendelian randomization approach.

Statistical inference in two-sample summary-data Mendelian randomization using robust adjusted profile score [PDF]
Mendelian randomization (MR) is a method of exploiting genetic variation to unbiasedly estimate a causal effect in presence of unmeasured confounding. MR is being widely used in epidemiology and other related areas of population science.
