Comparing marginal structural models to standard methods for estimating treatment effects of antihypertensive combination therapy
BACKGROUND Due to time-dependent confounding by blood pressure and differential loss to follow-up, it is difficult to estimate the effectiveness of aggressive versus conventional antihypertensive combination therapies in non-randomized comparisons. METHODS We utilized data from 22,576 hypertensive coronary artery disease patients, prospectively enrolled in the INternational VErapamil-Trandola...
متن کاملNonparametric Likelihood and Doubly Robust Estimating Equations for Marginal and Nested Structural Models
Drawing inferences about treatment effects is of interest in many fields. We consider Robins’s marginal and nested structural models and propose likelihood and regression estimators in the cross-sectional setting. First, we choose to retain a finite subset of all inherent and modelling constraints on the the joint distributions of potential outcomes and covariates under a correctly specified pr...
متن کاملHistory-adjusted marginal structural models for estimating time-varying effect modification.
Much of epidemiology and clinical medicine is focused on estimating the effects of treatments or interventions administered over time. In such settings of longitudinal treatment, time-dependent confounding is often an important source of bias. Marginal structural models (MSMs) are a powerful tool for estimating the causal effect of a treatment using observational data, particularly when time-de...
متن کاملMarginal structural models for partial exposure regimes.
Intensive care unit (ICU) patients are highly susceptible to hospital-acquired infections due to their poor health and many invasive therapeutic treatments. The effect on mortality of acquiring such infections is, however, poorly understood. Our goal is to quantify this using data from the National Surveillance Study of Nosocomial Infections in ICUs (Belgium). This is challenging because of the...
متن کاملAnalysis of longitudinal marginal structural models.
In this article we construct and study estimators of the causal effect of a time-dependent treatment on survival in longitudinal studies. We employ a particular marginal structural model (MSM), proposed by Robins (2000), and follow a general methodology for constructing estimating functions in censored data models. The inverse probability of treatment weighted (IPTW) estimator of Robins et al. ...
