Abstract

Introduction: Propensity score matching (PSM) is a statistical matching technique that attempts to estimate the effect of a treatment, or another intervention based on the covariates that predict whether the treatment will be received. PSM attempts to reduce bias due to confounding variables that can be found in an estimate of the treatment effect obtained from simply comparing the results between units that received the treatment versus those that did not.
