Meta-analysis of observational studies with unmeasured confounders.
Meta-analysis of observational studies is an exciting new area of innovation in statistical science. Unlike randomized controlled trials, which are the gold standard for proving causation, observational studies are prone to biases including confounding. In this article, we describe a novel Bayesian procedure to control for a confounder that is missing across the sequence of studies in a meta-...
متن کاملBayesian sensitivity analysis for unmeasured confounding in observational studies.
We consider Bayesian sensitivity analysis for unmeasured confounding in observational studies where the association between a binary exposure, binary response, measured confounders and a single binary unmeasured confounder can be formulated using logistic regression models. A model for unmeasured confounding is presented along with a family of prior distributions that model beliefs about a poss...
متن کاملSensitivity analysis and external adjustment for unmeasured confounders in epidemiologic database studies of therapeutics.
BACKGROUND Large health care utilization databases are frequently used to analyze unintended effects of prescription drugs and biologics. Confounders that require detailed information on clinical parameters, lifestyle, or over-the-counter medications are often not measured in such datasets, causing residual confounding bias. OBJECTIVE This paper provides a systematic approach to sensitivity a...
متن کاملSensitivity analysis for unmeasured confounders using an electronic spreadsheet.
In studies assessing the effects of a given exposure variable and a specific outcome of interest, confusion may arise from the mistaken impression that the exposure variable is producing the outcome of interest, when in fact the observed effect is due to an existing confounder. However, quantitative techniques are rarely used to determine the potential influence of unmeasured confounders. Sensi...
متن کاملClustered Treatment Assignments and Sensitivity to Unmeasured Biases in Observational Studies
in Observational Studies Ben B. Hansen, Paul R. Rosenbaum, and Dylan S. Small1 Abstract. Clustered treatment assignment occurs when individuals are grouped into clusters prior to treatment and whole clusters, not individuals, are assigned to treatment or control. In randomized trials, clustered assignments may be required because the treatment must be applied to all children in a classroom, or ...
