Matching and Propensity Scores
The popularity of matching techniques has increased considerably during the last decades. They are mainly used for matching treatment and control units in order to estimate causal treatment effects from observational studies or for integrating two or more data sets that share a common subset of covariates. In focusing on causal inference with observational studies, we discuss multivariate match...
متن کاملPropensity scores in cardiovascular research.
Propensity scores have been used to reduce bias in observational studies in many fields and are becoming more widely used in cardiovascular research.1 The goal of this statistical primer is to present the definition of propensity scores and to illustrate their use by describing some recent examples found in the cardiovascular disease research literature. Large-scale epidemiological cohort studi...

It is a collaborative network of research centers that support the rapid development of new scientific information and analytic tools. The DEcIDE network assists health care providers, patients, and policymakers seeking unbiased information about the outcomes, cli...
متن کاملMatching with Propensity Scores to Reduce Bias in Observational Studies
In observational studies subjects are not randomly assigned to treatment and control groups. Therefore, both groups can be significantly different from each other and their differences after applying a treatment cannot be attributed to the treatment effect. Propensity scores methods offer a way to balance groups by matching treatment and control units based on a set of covariates. This paper ex...
متن کاملPropensity score interval matching: using bootstrap confidence intervals for accommodating estimation errors of propensity scores
BACKGROUND Propensity score methods have become a popular tool for reducing selection bias in making causal inference from observational studies in medical research. Propensity score matching, a key component of propensity score methods, normally matches units based on the distance between point estimates of the propensity scores. The problem with this technique is that it is difficult to estab...
