13 de mar. de 2015 · Go to: Step 1. Calculating the Propensity Score. The propensity score is the probability of receiving one of the treatments being compared, given the measured covariates. Covariates are the variables included in the study that are not the outcome or the exposure of interest; they could be confounders or not.
1 de dic. de 2014 · Similarly, Song et al. (2012) fit separate propensity score models for each time point, equating the treatment and control groups at each time point. That strategy may be particularly appealing when in a difference-indifference type framework with a treatment group and a comparison group, but where there are more than two time periods available (also known as a comparative interrupted time ...
6 de mar. de 2023 · Background There is inconclusive evidence regarding the effectiveness of extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA) patients. We aimed to evaluate the association between ECPR and neurologic recovery in OHCA patients using time-dependent propensity score matching analysis. Methods Using a nationwide OHCA registry, adult medical OHCA patients ...
15 de jun. de 2023 · In this retrospective study, we compared the efficacy and safety of lenvatinib plus sintilimab, with or without transarterial chemoembolization (TLS vs. LS), in patients with intermediate or advanced stage hepatocellular carcinoma (HCC). Eligible patients who received combination therapy with TLS or …
2 de oct. de 2018 · Covariate Distribution Balance via Propensity Scores. Pedro H. C. Sant'Anna, Xiaojun Song, Qi Xu. This paper proposes new estimators for the propensity score that aim to maximize the covariate distribution balance among different treatment groups. Heuristically, our proposed procedure attempts to estimate a propensity score model by making the ...

Propensity score matching. In the statistical analysis of observational data, propensity score matching ( PSM) is a statistical matching technique that attempts to estimate the effect of a treatment, policy, or other intervention by accounting for the covariates that predict receiving the treatment. PSM attempts to reduce the bias due to ...
