Bias estimation in study design: a meta-epidemiological analysis of transcatheter versus surgical aortic valve replacement

Abstract Background Paucity of RCTs of non-drug technologies lead to widespread dependence on non-randomized studies. Relationship between nonrandomized study design attributes and biased estimates of treatment effects are poorly understood. Our purpose was to estimate the bias associated with speci...
