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 ...

Adding propensity scores to pure prediction models fails to improve predictive performance [PDF]

open access: yesPeerJ, 2013
Background. Propensity score usage seems to be growing in popularity leading researchers to question the possible role of propensity scores in prediction modeling, despite the lack of a theoretical rationale. It is suspected that such requests are due to

Propensity score weighting for covariate adjustment in randomized clinical trials [PDF]

open access: yesStatistics in Medicine, 2020
Chance imbalance in baseline characteristics is common in randomized clinical trials. Regression adjustment such as the analysis of covariance (ANCOVA) is often used to account for imbalance and increase precision of the treatment effect estimate. An objective alternative is through inverse probability weighting (IPW) of the propensity scores. Although

Cutting Feedback in Bayesian Regression Adjustment for the Propensity Score [PDF]

open access: yesThe International Journal of Biostatistics, 2010
McCandless, Gustafson and Austin (2009) describe a Bayesian approach to regression adjustment for the propensity score to reduce confounding. A unique property of the method is that the treatment and outcome models are combined via Bayes theorem. However, this estimation procedure can be problematic if the outcome model is misspecified.

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.

Will land circulation sway "grain orientation"? The impact of rural land circulation on farmers' agricultural planting structures.

open access: yesPLoS ONE, 2021
This study calculates the effect of different types of land circulation on farmers' decision-making regarding agricultural planting structure, using field survey data involving 1,120 households in Hubei province, China, and PSM (propensity score matching)

Accounting for the mortality benefit of drug-eluting stents in percutaneous coronary intervention: a comparison of methods in a retrospective cohort study

open access: yesBMC Medicine, 2011
Background Drug-eluting stents (DES) reduce rates of restenosis compared with bare metal stents (BMS). A number of observational studies have also found lower rates of mortality and non-fatal myocardial infarction with DES compared with BMS, findings not

Pre-Treatment Neutrophil Count as a Predictor of Antituberculosis Therapy Outcomes: A Multicenter Prospective Cohort Study

open access: yesFrontiers in Immunology, 2021
BackgroundNeutrophils have been associated with lung tissue damage in many diseases, including tuberculosis (TB). Whether neutrophil count can serve as a predictor of adverse treatment outcomes is unknown.MethodsWe prospectively assessed 936 patients ...
