Analysis of Longitudinal Data With Missing Responses: A Study of Pain Control Cost
… complete imputed daily cost data are produced. A generalized estimating equations (GEE) model, is then applied to conduct analysis on each set of data, producing multiple analysis results. The correlation between observations within patients is presented in an AR-1 working correlation structure. …

Model Robust Regression Based on Generalized Estimating Equations
… on local estimation with a global, parametric generalized estimating equations (GEE) estimate through a mixing parameter on both the mean scale and the linear predictor scale. As a special case, when data are uncorrelated, this amounts to mixing a local likelihood estimate with predictions from …

Disparities in Admission and Pediatric Emergency Outcomes by Race, Ethnicity, and Language.
… wait times, and unexpected return ED visits. Generalized estimating equations (GEE) and Cox proportional hazard models were used to assess the association between REaL and patient outcomes. Results: 35,180 patient encounters were analyzed. White patients had significantly higher adjusted odds …

The Effect of Birth Order on Infant Injury
… “severe injury event.” Data was analyzed using generalized estimating equations (GEE). Birth order was associated with infant injury events and severe infant injury events. Birth order 4th or greater had the greatest effect for both injury outcomes. Additionally, several maternal characteristics …

Markov Chain Marginal Bootstrap for Generalized Estimating Equations
… repeated measures over time on each subject. The generalized estimating equations (GEE) approach (Liang and Zeger, 1996) has been widely used for the analysis of longitudinal data. The ordinary GEE approach can be robustified through the use of truncated robust estimating functions. Statistical …

Migrations and gradations : reappraising the health profile of immigrants to Canada
… attainment, occupational opportunity) of non-refugee immigrants and existing screening protocols that admit only the healthiest of persons to Canada. It has been suggested that this health advantage diminishes as the time of residence in Canada increases, due in part to the adoption of health-risk …

Influência da manipulação do foco atencional sobre a atenção seletiva visual, tempo de reação e capacidade funcional de mulheres idosas praticantes do método Pilates
… Statistical analyses were performed using Generalized Estimating Equations (GEE), with gamma distribution for asymmetric variables and normal distribution for symmetric variables. Additionally, effect size analyses (Cohen’s d) and association tests between engagement and focus type …

Dynamic models for time-varying outcomes: An application to the 2015-2017 patient cohort on antiretroviral therapy at Luderitz hospital, Namibia
… visits. This study used mixed effects model and Generalized Estimating Equations (GEE) to model longitudinally measured viral load as a function of the dynamic as well as non-dynamic covariates. To account for missingness in the outcome variable as well as potential measurement error in …

Individual Resilience, Social Support, and Health Risk Behaviors in Adolescents and Young Adults: Study on Cross-sectional and Longitudinal Samples
… data were analyzed using logistic regression and Generalized Estimating Equations (GEE) models. The results showed that resilience status in general and adversity populations varied over time. However, when viewed over a long period of lifetime, individual resiliency on health risk behaviors …

Loneliness in the oldest old
… transitions. Cox regression models and generalized estimating equations (GEE) were used to explore the effects of loneliness on all-cause mortality, cognitive decline, and health service and social care utilisation, respectively. The findings reveal clear associations between loneliness …

Evaluation of a Prescription Drug Pay-for-Performance Program: Impact on Prescribing Trends, Budget, and Patient Outcomes
… and non-participating clinics using generalized estimating equations (GEE). Using interview survey data, we sought to understand program elements that may be important predictors of engagement in and success with this type of program. We calculated budget savings as a result of …

Predictors of Carbapenem Resistant Gram-negative Bacteria in a Consortium of Academic Medical Center Hospitals
… isolation was generated as a binary outcome. Generalized estimating equations (GEE) were used to model CR-KP and CR-PA. Results: CR-KP rates (1000PDs) increased from 0.07 in 2006 to 0.15 in 2009 (P= 0.0118) and CR-KP proportions increased from 1.3% in 2006 to 3.1% in 2009 (0.0003) within 40 …

Arthritis impact on the physical function, disability, and health-related quality of life among older Mexican-Americans
… also obtained. General linear mixed models and generalized estimating equations (GEE) were used to examine the time effect on: 1) each stage of the disablement process and 2) physical and mental HRQoL over three points of time (2000-2001, 2001-2002, and 2006). This study conforms to STROBE …

Strain, depression, and adolescent substance use: A temporal-ordering analysis
… to reduce depression and substance use. Using generalized least squares regression (GLS) for panel data for depression and generalized estimating equations (GEE) for panel data in STATA for the dichotomous substance use outcomes, results indicated that stressful events measured in the past were …

An Empirical Investigation of Kaizen Event Effectiveness: Outcomes and Critical Success Factors
… factors are analyzed through regression, using generalized estimating equations (GEE) to account for potential correlation in residuals within organizations. The research found a significant positive correlation between the two social system outcomes (attitude toward Kaizen events and employee …
