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

open access: yesInternational Journal of Turkish Education Sciences, 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 ...

Head to head comparison of the propensity score and the high-dimensional propensity score matching methods

open access: yesBMC Medical Research Methodology, 2016
Background Comparative performance of the traditional propensity score (PS) and high-dimensional propensity score (hdPS) methods in the adjustment for confounding by indication remains unclear.

Weight trimming and propensity score weighting.

open access: yesPLoS ONE, 2011
Propensity score weighting is sensitive to model misspecification and outlying weights that can unduly influence results. The authors investigated whether trimming large weights downward can improve the performance of propensity score weighting and ...

Robust Causal Estimation from Observational Studies Using Penalized Spline of Propensity Score for Treatment Comparison

open access: yesStats, 2021
Without randomization of treatments, valid inference of treatment effects from observational studies requires controlling for all confounders because the treated subjects generally differ systematically from the control subjects.

Efficiency of Average Treatment Effect Estimation When the True Propensity Is Parametric

open access: yesEconometrics, 2019
It is well known that efficient estimation of average treatment effects can be obtained by the method of inverse propensity score weighting, using the estimated propensity score, even when the true one is known.

Optimal caliper width for propensity score matching of three treatment groups: a Monte Carlo study. [PDF]

open access: yesPLoS ONE, 2013
Propensity score matching is a method to reduce bias in non-randomized and observational studies. Propensity score matching is mainly applied to two treatment groups rather than multiple treatment groups, because some key issues affecting its application

Propensity scores and the surgeon

open access: yesBritish Journal of Surgery, 2006
AbstractBackgroundEvidence-based surgery has been established as a cornerstone of good clinical practice, promising to improve the treatment of patients and the quality of surgical education. However, evidence-based surgery requires dedicated clinicians trained to perform methodologically sound clinical investigations.

Association of hypertension and incident diabetes in Chinese adults: a retrospective cohort study using propensity-score matching

open access: yesBMC Endocrine Disorders, 2021
Background Reliable quantification of the relationship between hypertension and diabetes risk is limited, especially among Chinese people. We aimed to investigate the association between hypertension and the risk of diabetes in a large cohort of the ...

A brief introduction to propensity score for anesthesiologists [PDF]

open access: yesKorean Journal of Anesthesiology, 2020
Intergroup comparability is of paramount importance in clinical research since it is impossible to draw conclusions on a treatment if populations with different characteristics are compared.
