DOI: 10.1002/gepi.22455
Abstract: Genome‐wide association studies have provided many genetic markers that can be used as instrumental variables to adjust for confounding in epidemiological studies. Recently, the principle has been applied to other forms of bias in observational… read more here.

DOI: 10.1038/s41467-022-28119-9
Abstract: Estimated genetic associations with prognosis, or conditional on a phenotype (e.g. disease incidence), may be affected by collider bias, whereby conditioning on the phenotype induces associations between causes of the phenotype and prognosis. We propose… read more here.

DOI: 10.1093/jamia/ocad013
Abstract: OBJECTIVES Collider bias is a common threat to internal validity in clinical research but is rarely mentioned in informatics education or literature. Conditioning on a collider, which is a variable that is the shared causal… read more here.

DOI: 10.1093/nutrit/nuac077
Abstract: Obesity paradoxes have been reported in many diseases to date. As the wording "paradox" indicates, our intuition rejects the hypothesis that obese people have a better life expectancy or fewer cardiovascular events. One of the… read more here.

DOI: 10.1136/bjsports-2018-100054
Abstract: The medical condition of hyperandrogenism has entered common parlance because the International Association of Athletics Federation (IAAF) decided to ban women with the condition from competing against women who have ‘normal’ levels of testosterone (see… read more here.
