Dr C Mary Schooling and colleagues publish in the American Journal of Epidemiology: Mendelian randomization and estimation of treatment efficacy for chronic disease. This article, featured as “Editor’s choice” explains how the new analytic strategy of Mendelian randomization provides information complimentary to the ‘gold standard evidence’ from randomized controlled trials. Traditionally, randomized controlled trials assess whether a particular intervention works, whilst Mendelian randomization studies can help identify the ‘magic’ ingredient in an intervention and thus facilitate translation of interventions to new settings.
