A review of the use of propensity score diagnostics in papers published in high-ranking medical journals

open access: yesBMC Medical Research Methodology, 2020
Background Propensity scores are widely used to deal with confounding bias in medical research. An incorrectly specified propensity score model may lead to residual confounding bias; therefore it is essential to use diagnostics to assess propensity ...

Comparison of Propensity Score Weighting Methods to Remove Selection Bias in Average Treatment Effect Estimates

open access: yesUluslararası Türk Eğitim Bilimleri Dergisi, 2023
In this Monte Carlo simulation study, the performance of six different propensity score methods implemented through weighting cases was investigated: inverse probability of treatment weighting, truncated inverse probability of treatment weighting ...

Applying Propensity Score Methods in Clinical Research in Neurology

open access: yesNeurology, 2021
Propensity score–based analysis is increasingly being used in observational studies to estimate the effects of treatments, interventions, and exposures. We introduce the concept of the propensity score and how it can be used in observational research. We

Covariate balance-related propensity score weighting in estimating overall hazard ratio with distributed survival data

open access: yesBMC Medical Research Methodology, 2023
Background When data is distributed across multiple sites, sharing information at the individual level among sites may be difficult. In these multi-site studies, propensity score model can be fitted with data within each site or data from all sites when ...

An Introduction to Propensity Score Methods for Reducing the Effects of Confounding in Observational Studies

open access: yesMultivariate Behavioral Research, 2011
The propensity score is the probability of treatment assignment conditional on observed baseline characteristics. The propensity score allows one to design and analyze an observational (nonrandomized) study so that it mimics some of the particular ...

A Comparison of Propensity Score and Linear Regression Analysis of Complex Survey Data

open access: yesJournal of Data Science, 2021
We extend propensity score methodology to incorporate survey weights from complex survey data and compare the use of multiple linear regression and propensity score analysis to estimate treatment effects in observational data from a complex survey.

Some Practical Guidance for the Implementation of Propensity Score Matching

open access: yesSocial Science Research Network, 2008
Propensity Score Matching (PSM) has become a popular approach to estimate causal treatment effects. It is widely applied when evaluating labour market policies, but empirical examples can be found in very diverse fields of study.
