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

PLoS 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

Genetic matching for time-dependent treatments: a longitudinal extension and simulation study

BMC Medical Research Methodology, 2023
Background Longitudinal matching can mitigate confounding in observational, real-world studies of time-dependent treatments. To date, these methods have required iterative, manual re-specifications to achieve covariate balance.

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

Uluslararası 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 ...

Evaluating the performance of propensity score matching based approaches in individual patient data meta-analysis

BMC Medical Research Methodology, 2021
Background Individual-patient data meta-analysis (IPD-MA) is an increasingly popular approach because of its analytical benefits. IPD-MA of observational studies must overcome the problem of confounding, otherwise biased estimates of treatment effect may

Applications of propensity score matching: a case series of articles published in [PDF]

Annals of Coloproctology, 2022
Propensity score matching (PSM) is an increasingly applied method of ensuring comparability between groups of interest. However, PSM is often applied unconditionally, without precise considerations.

Using matching methods to account for selection bias in Norway’s Primary Care Teams (PCT) pilot

Nordic Journal of Health Economics, 2021
Norway is piloting team-based primary care delivery models: Honorarmodellen (HM) and Driftstilskuddsmodellen (DM). In addition to organisational changes, the DM transforms provider payment, which seems to attract specific practices.
