[A Monte-Carlo study for propensity score methods].

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

Here, the author make a summary include mensuration and questionnaire of the cataract related Quality of life, result of the QOL and it's affect factor after the cataract surgery, the relationship between the QOL and other visual test, and the attentions while using the QOL measure, etc.
