What is propensity score modelling?
Emerg Med J. 2017 Mar;34(3):129-131
Authors: Campbell MJ
Abstract
Propensity score methodology is being increasingly used to try and make inferences about treatments when randomised trials are either impossible or not conducted and the only data are from observational studies. This paper reviews the basis of propensity scores and the current state of knowledge about them. It uses and critiques a current paper in the Emergency Medicine Journal to illustrate the methodology.
