ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the statistical property of the estimators on exposure effect and value of propensity score methods in practical use.</p><p><b>METHODS</b>Simulation data, propensity score methods (PSM) were conducted to assess bias and efficiency, under both with/without model misspecification conditions.</p><p><b>RESULTS</b>Under model misspecification conditions, propensity score methods had better robustness than model based methods.</p><p><b>CONCLUSION</b>For large and complicated data, propensity score methods had more flexibility in practical use than model based methods.</p>
