Statin Treatment and Clinical Outcomes of Heart Failure Among Africans: An Inverse Probability Treatment Weighted Analysis

Journal of the American Heart Association, 2017
Background Randomized control trials of statins have not demonstrated significant benefits in outcomes of heart failure ( HF ). However, randomized control trials may not always be generalizable. The aim was to determine whether statin and statin type–lipophilic or –hydrophilic improve

Impact of age on the outcomes of extracorporeal cardiopulmonary resuscitation: analysis using inverse probability of treatment weighting

European Journal of Cardio-Thoracic Surgery, 2021
Abstract OBJECTIVESPatient selection is crucial to improving the outcomes of extracorporeal cardiopulmonary resuscitation (ECPR). However, ECPR’s efficacy with older patients remains unknown.METHODSWe reviewed patients who underwent extracorporeal membrane oxygenation (ECMO) for refractory cardiac arrest from January 2006 to December 2018.

A comparison of short-term therapeutic efficacy between infliximab and tacrolimus for moderate to severe ulcerative colitis

Romanian Journal of Internal Medicine, 2017
Introduction. Both infliximab (IFX) and tacrolimus (Tac) are effective for inducing clinical remission in patients with ulcerative colitis (UC). However, no randomized study has addressed the relative efficacies of IFX and Tac for patients with moderate ...

Pragmatic trials: ignoring a mediator and adjusting for confounding

BMC Research Notes, 2019
Objectives In pragmatic trials, the new treatment is compared with usual care (heterogeneous control arm) that makes the comparison of the new treatment with each treatment within the control arm more difficult.

On flexible inverse probability of treatment and intensity weighting: Informative censoring, variable selection, and weight trimming

Statistical Methods in Medical Research
Many observational studies feature irregular longitudinal data, where the observation times are not common across individuals in the study. Furthermore, the observation times may be related to the longitudinal outcome. In this setting, failing to account for the informative observation process may result in biased causal estimates.

Estimating Marginal Hazard Ratios by Simultaneously Using A Set of Propensity Score Models: A Multiply Robust Approach [PDF]

, 2020
The inverse probability weighted Cox model is frequently used to estimate marginal hazard ratios. Its validity requires a crucial condition that the propensity score model is correctly specified.
