Efficacy and Safety of Antiplatelet Therapy After Endovascular Aortic Repair: A Target Trial Emulation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The optimal antiplatelet regimen after standard endovascular aneurysm repair (EVAR) in patients without atherosclerotic cardiovascular disease remains uncertain.

Impacts of trans‐anal tube placement in patients with sigmoid colon cancer: Risk verification analysis using inverse probability weighting analysis

Annals of Gastroenterological Surgery, 2023
Purpose Anastomotic leakage (AL) is a serious postoperative complication that affects short‐ and long‐term outcomes. The use of a trans‐anal drainage tube (TDT) is reported to prevent AL in rectal cancer patients, but its value in sigmoid colon cancer ...

Effect Estimate of Time-varying Social Support and Trust on the Physical and Mental Health of Mothers at 2.5 Years Postpartum: The Japan Environment and Children’s Study (JECS)

Journal of Epidemiology, 2023
Background: Many epidemiological studies have reported the association between various social factors and health status in mothers during and after pregnancy. However, little is known about their joint and longitudinal impact. We examined the association

A General Double Robustness Result for Estimating Average Treatment Effects [PDF]

, 2014
In this paper we study doubly robust estimators of various average treatment effects under unconfoundedness. We unify and extend much of the recent literature by providing a very general identification result which covers binary and multi-valued ...

A Generalized Bootstrap Procedure of the Standard Error and Confidence Interval Estimation for Inverse Probability of Treatment Weighting

Multivariate Behavioral Research, 2023
The inverse probability of treatment weighting (IPTW) approach is commonly used in propensity score analysis to infer causal effects in regression models. Due to oversized IPTW weights and errors associated with propensity score estimation, the IPTW approach can underestimate the standard error of causal effect.

Efficacy Studies of Malaria Treatments in Africa: Efficient Estimation with Missing Indicators of Failure [PDF]

, 2005
Efficacy studies of malaria treatments can be plagued by indeterminate outcomes for some patients. The study motivating this paper defines the outcome of interest (treatment failure) as recrudescence and for some subjects, it is unclear whether a ...

Entropy balancing is doubly robust

, 2016
Covariate balance is a conventional key diagnostic for methods used estimating causal effects from observational studies. Recently, there is an emerging interest in directly incorporating covariate balance in the estimation.

On variance of the treatment effect in the treated using inverse probability weighting

, 2020
In the analysis of observational studies, inverse probability weighting (IPW) is commonly used to consistently estimate the average treatment effect (ATE) or the average treatment effect in the treated (ATT). The variance of the IPW ATE estimator is often estimated by assuming the weights are known and then using the so-called "robust" (Huber-White ...

How to Control for Many Covariates? Reliable Estimators Based on the Propensity Score [PDF]

We investigate the finite sample properties of a large number of estimators for the average treatment effect on the treated that are suitable when adjustment for observable covariates is required, like inverse probability weighting, kernel and other ...
