Estimation of place-based vulnerability scores for HIV viral non-suppression: an application leveraging data from a cohort of people with histories of using drugs

Autor: Trang Quynh Nguyen, Laken C. Roberts Lavigne, Carly Lupton Brantner, Gregory D. Kirk, Shruti H. Mehta, Sabriya L. Linton

Publikováno v: BMC Medical Research Methodology, Vol 24, Iss 1, Pp 1-17 (2024)

Abstract The relationships between place (e.g., neighborhood) and HIV are commonly investigated. As measurements of place are multivariate, most studies apply some dimension reduction, resulting in one variable (or a small number of variables), which

Sensitivity analyses for effect modifiers not observed in the target population when generalizing treatment effects from a randomized controlled trial: Assumptions, models, effect scales, data scenarios, and implementation details.

Autor: Trang Quynh Nguyen, Benjamin Ackerman, Ian Schmid, Stephen R Cole, Elizabeth A Stuart

Publikováno v: PLoS ONE, Vol 13, Iss 12, p e0208795 (2018)

BackgroundRandomized controlled trials are often used to inform policy and practice for broad populations. The average treatment effect (ATE) for a target population, however, may be different from the ATE observed in a trial if there are effect modi

Flexible propensity score estimation strategies for clustered data in observational studies

Autor: Ting‐Hsuan Chang, Trang Quynh Nguyen, Youjin Lee, John W. Jackson, Elizabeth A. Stuart

Publikováno v: Stat Med

Existing studies have suggested superior performance of nonparametric machine learning over logistic regression for propensity score estimation. However, it is unclear whether the advantages of nonparametric propensity score modeling are carried to s

Effectiveness of a Multicomponent Strategy for Implementing Guidelines for Treating Tobacco Use in Vietnam Commune Health Centers

Autor: Donna Shelley, Charles M. Cleland, Nina Siman, Minh Hoang Van, Nam Nguyen, Nancy VanDevanter, Trang Quynh Nguyen

Publikováno v: Nicotine Tob Res

Introduction Strategies are needed to increase implementation of evidence-based tobacco dependence treatment (TDT) in health care systems in low-and middle-income countries (LMICs). Aims and Methods We conducted a two-arm cluster randomized controlle

Partially Pooled Propensity Score Models for Average Treatment Effect Estimation with Multilevel Data

Autor: Trang Quynh Nguyen, Youjin Lee, Elizabeth A. Stuart

Publikováno v: Journal of the Royal Statistical Society Series A: Statistics in Society. 184:1578-1598

Causal inference analyses often use existing observational data, which in many cases has some clustering of individuals. In this paper, we discuss propensity score weighting methods in a multilevel setting where within clusters individuals share unme

Quality of Life Among Caregivers of a Vulnerable Population Living with HIV: Caregiving and Relationship Factors

Autor: Zachary Catanzarite, Tuo Yen Tseng, Sarina R. Isenberg, Trang Quynh Nguyen, Amy R. Knowlton, Dulce M. Cruz-Oliver, Mary M. Mitchell

Publikováno v: AIDS and Behavior. 25:360-376

Literature on health-related quality of life (HRQOL) has focused on people living with chronic conditions, with less attention given to HRQOL among informal caregivers. We used cross-sectional dyadic data from both care recipients (CR) living with HI

Propensity Score Analysis With Latent Covariates: Measurement Error Bias Correction Using the Covariate’s Posterior Mean, aka the Inclusive Factor Score

Autor: Elizabeth A. Stuart, Trang Quynh Nguyen

Publikováno v: Journal of Educational and Behavioral Statistics. 45:598-636

We address measurement error bias in propensity score (PS) analysis due to covariates that are latent variables. In the setting where latent covariate $X$ is measured via multiple error-prone items $\mathbf{W}$, PS analysis using several proxies for
