Marginal structural models for multilevel clustered data.

Publication Type: Academic Journal

Source(s): Biostatistics (Oxford, England) [Biostatistics] 2022 Oct 14; Vol. 23 (4), pp. 1056-1073.

Abstract: Marginal structural models (MSMs), which adopt inverse probability treatment weighting in the estimating equations, are powerful tools to estimate the causal effects of time-varying exposures in the presence of time-dependent confounders. Motivated by ...

Marginal Structural Models for Life-Course Theories and Social Epidemiology: Definitions, Sources of Bias, and Simulated Illustrations.

Publication Type: Academic Journal

Source(s): American journal of epidemiology [Am J Epidemiol] 2022 Jan 24; Vol. 191 (2), pp. 349-359.

Abstract: Social epidemiology aims to identify social structural risk factors, thus informing targets and timing of interventions. Ascertaining which interventions will be most effective and when they should be implemented is challenging because social condition...

Using marginal structural models to analyze the impact of subsequent therapy on the treatment effect in survival data: Simulations and clinical trial examples.

Publication Type: Academic Journal

Source(s): Pharmaceutical statistics [Pharm Stat] 2021 Nov; Vol. 20 (6), pp. 1088-1101. Date of Electronic Publication: 2021 Apr 27.

Authors:

Abstract: We explore the impact of time-varying subsequent therapy on the statistical power and treatment effects in survival analysis. The marginal structural model (MSM) with stabilized inverse probability treatment weights (sIPTW) was used to account for the ...

Structural model of microtubule dynamics inhibition by kinesin-4 from the crystal structure of KLP-12-tubulin complex.

Publication Type: Academic Journal

Source(s): eLife. 9/6/2022, p1-27. 27p.

Abstract: Kinesin superfamily proteins are microtubule-based molecular motors driven by the energy of ATP hydrolysis. Among them, the kinesin-4 family is a unique motor that inhibits microtubule dynamics. Although mutations of kinesin-4 cause several diseases, i...

Using marginal structural models to analyze randomized clinical trials with non-adherence and lost to follow up.

Publication Type: Academic Journal

Source(s): Annals of epidemiology [Ann Epidemiol] 2021 Nov; Vol. 63, pp. 22-28. Date of Electronic Publication: 2021 Jul 18.

Abstract: Background: In the presence of non-adherence and lost to follow up, results of an Intention to Treat (ITT) analysis may be biased as it is measuring the effect of assignment rather than the effect of treatment. Given that Marginal Structural Models (MS...

The Cointegrated VAR Model with Deterministic Structural Breaks.

Publication Type: Academic Journal

Source(s): Central European Journal of Economic Modelling & Econometrics. 2022, Vol. 14 Issue 3, p335-350. 16p.

Abstract: The presence of a binary variable in the cointegrated VAR (CVAR) model is most often interpreted as the structural break affecting the data generating process. It is proved in the paper that to enjoy this interpretation the binary variable must appear ...
