Perilous Polities? Regime Transition and Conflict 1950-2000
… propensity of transitioning states. Employing a generalized estimating equation with logit and poisson specifications, the results show that change towards democracy decreases the probability of involvement in militarized inter-state disputes and wars. However, uneven or "rocky" transitions are …

A pilot comparison of first morning versus 24-hour urinary deoxynivalenol in UK adults
… evaluate variability in DON concentrations and generalized estimating equation (GEE) models were used to assess the relationship between collection types. Greater between-person variability was observed in 24-hour collections, unadjusted and adjusted for creatinine (ICC=0.78 and 0.56, …

Censored Regression Models With Applications to Infrastructure Degradation Studies
… measurements, random effect models and generalized estimating equation methods for censored data are developed. A general argument about the theoretical bias for the GEE method, both in the censored and uncensored case, provides a criteria for deciding when marginal analysis is …

Functional Near-Infrared Spectroscopy (fNIRS) Based Functional Connectivity Alterations Associated with Delirium in Critically Ill Children: An Exploratory Study
… compared to non-delirious ones on average. Generalized estimating equation (GEE) modelling revealed that increased functional connectivity between the right temporal and left temporoparietal regions was independently associated with delirium presence, even after false discovery rate (FDR) …

In Vitro Study Comparing Treatments for Incipient Enamel Lesion Remineralization
… ANOVA with Tukey-Kramer post hoc tests and Generalized Estimating Equation (GEE) modeling. Results: SDF demonstrated the lowest microhardness values, with a mean of 147.24 (SD: 39.76) at 100 μm, significantly lower than FV (276.54; SD: 33.72), Icon (254.59; SD: 30.18), and the control …

RESPIRATORY PARAMETERS, PULMONARY REHABILITATION and SURVIVAL in COVID-19 PATIENTS
… performed to assess the sample characteristics. Generalized estimating equation models was used to assess survival. Multivariate regression was used to assess improvement in physical function. Kaplan curve analysis was performed to assess participation of PR and morbidity. Results: Being younger, …

Accounting for spatial confounding in large scale epidemiological studies
… I demonstrate these methods for mixed models, generalized estimating equation models, and a proportional hazard regression framework. I demonstrate the application of these methods in a study of tropical cyclone wind exposures on preterm birth in a North Carolina cohort.

Characterizing perinatal depression and its impact on infant outcomes and maternal-nurse SMS communication in a cohort of Kenyan women
… gestation) and follow-up (14 weeks postpartum). Generalized estimating equation (GEE) with Poisson link was used to evaluate correlates of perinatal depression, infant outcomes, and frequency of SMS messaging. Results: Of the 572 women with complete follow-up information, 188 (32.9%) had evidence …

Exploring the Discourse Attributes of Referential Process in Emotion Focused and Cognitive Behavioural Therapies for Depression
… and two sessions belonged to each client, Generalized Estimating Equation (GEE) was used to account for the nested structure of the data. The DAAP measures differed between EFT and CBT in the expected ways based on the theories of change that are rooted in each modality: there were more …

Vision Impairment and Health Outcomes among Older Mexican Americans: Findings from the Hispanic Established Population for the Epidemiologic Study of the Elderly
… and hearing impairment as covariates. Analysis: Generalized estimating equation models were performed to estimate the odds ratio of health outcomes and health care utilization. Results: Percent of VI ranged from 3.7% to 4.3% for near vision impairment (NVI), 12.9% to 27.8% for distant vision …

An Assessment of Direct Mortality to Avifauna from Wind Energy Facilities in North Dakota and South Dakota
… at TAWF and EKWF, respectively. We used a Generalized Estimating Equation (GEE) to estimate the influence of landscape variables around individual turbines on waterfowl mortality and documented cropland to have a negative influence on mortality rates. We suggest future wind facility siting …

Effectiveness of Saskatchewan Government Insurance 2014 Traffic Safety Initiatives on Reducing Casualties
… analysis, Negative Binomial (NB) and Generalized Estimating Equation (GEE) were used to analyze the data variables. In the end, this research identified the most effective initiative and recommended how the initiatives could be improved to obtain maximum efficiency in safety as …

Do weight status and weight perception predict academic acheivement in adolescents? A longitudinal analysis of the COMPASS study.
… 7 (2018/2019) of the COMPASS study were used. Generalized estimating equation models were used to examine associations between students’ BMI classification and weight perception and their math and English/French course grades and post-secondary academic aspirations and expectations. All models …

The Use of Individual Participant Data (IPD) for Examining Heterogeneity in Meta-analysis of Observational Studies: An Application to Biomechanical Workplace Risk Factors and Low Back Pain
… common metric. IPD analyses were conducted using generalized estimating equation (GEE) regression to identify variables that acted as strong confounders and effect modifiers. Traditional AD meta-analysis was also conducted and potential sources of heterogeneity were tested using meta-regression. …

Eating Frequency, Disease-Related Biomarkers and Appetite
… of hunger, desire to eat, and 100-fullness. The generalized estimating equation modification of linear regression was used to compare fasting plasma biomarkers and mean ratings of subjective appetite. A total of 15 participants completed both study phases (4 males, 11 females). Mean (± SD) age …

Flexible models and methods for longitudinal and multilevel functional data
… Index greater than or equal to 95. Based on generalized estimating equation (GEE) models, a previous parametric analysis showed that the functional status declines over time and the trajectories of decline are different depending on insurance status. The trend in functional status may not be …

The impact of medication therapy management on polypharmacy in people living with HIV/AIDS
… by PLWHA. A longitudinal data analysis using a generalized estimating equation was used to assess the impact of MTM intervention on polypharmacy over time by determining the change in polyactive substances in medication pre-post MTM intervention. The relationship between the changes in HIV …

The impact of a comic book intervention on increasing East African-American adolescents’ HPV vaccine-related knowledge, attitudes and intentions to receive vaccine
… were compared with chi-squared tests. We used generalized estimating equation (GEE) models to estimate relative risks (RRs) and 95% confidence intervals (CIs) to measure the magnitude of the impact of the intervention on each construct. We also stratified the GEE models by gender to enumerate …

Modifications of Q-learning to Optimize Dynamic Treatment Regimes
… interested in identifying the optimal DTR and estimating the outcome trajectory under the optimal DTR. However, in the presence of stagewise repeated-measures outcomes, standard Q-learning fails to provide point estimates of the optimal trajectory with time-specific heterogeneous causal …
