Beta Regression Models For Repeated-Measures Data Analysis, Nicholas A. Hein
Beta Regression Models For Repeated-Measures Data Analysis, Nicholas A. Hein
Theses & Dissertations
Bounded data often give rise to uncorrectable skew and heteroscedasticity. Bounded data are a relatively frequent occurrence in clinical and research settings. For example, in neuropsychology, most neurocognitive tests are bounded, and subjects are repeatedly measured over time. The statistician needs to choose a model that accounts for the correlated nature of the repeated measures. The Beta distribution is a natural choice for modeling bounded data. Currently, generalized linear mixed models (GLMM) and generalized estimating equations (GEE) are two methods that can be used to model Beta distributed data with repeated measures. However, GLMMs and GEEs have limitations, i.e., GLMMs …
Association Of Copy Number Variations With Chronic Hepatitis B In Chinese Population, Fang Niu
Association Of Copy Number Variations With Chronic Hepatitis B In Chinese Population, Fang Niu
Capstone Experience
With one third of the Hepatitis B virus (HBV) infection population of the world, chronic Hepatitis B (CHB) has become a top burden in China. CHB is a lifelong infection with HBV which can cause serious health problems, like cirrhosis, liver cancer or even death. HBV infection is known to result in various clinical conditions, including asymptomatic HBV carriers to chronic hepatitis and primary hepatocellular carcinoma. Several studies have shown that host genetic susceptibility could be an important factor that determines these various outcomes of HBV infection. Many Single Nucleotide Polymorphisms (SNPs) and Copy Number Variations (CNVs) have been associated …
Effects Of Perioperative Hyperglycemia In Patients With Diabetes Compared To Patients Without Diabetes: A Retrospective Study Of Treatment And Outcomes, Matthew Anderson
Effects Of Perioperative Hyperglycemia In Patients With Diabetes Compared To Patients Without Diabetes: A Retrospective Study Of Treatment And Outcomes, Matthew Anderson
Capstone Experience
The main goal of this project was to examine the differences in perioperative hyperglycemia treatment received by patients with a diagnosis of diabetes mellitus (DM) and patients without a diagnosis of diabetes (NDM); and how these treatment differences can affect the length of hospital stay. Studies have revealed that, when comparing DM and NDM patients with the same degree of perioperative hyperglycemia, NDM patients suffer worse outcomes. It has been suggested in previous research that this may be because NDM patients receive treatment that does not measure up to the standard of care treatment that DM patients receive. In this …
Saturated Fat Intake Is Associated With Lung Function In Individuals With Airflow Obstruction: Results From Nhanes 2007⁻2012, Kasey Cornell, Morshed Alam, Elizabeth Lyden, Lisa Wood, Tricia D. Levan, Tara M. Nordgren, Kristina L. Bailey, Corrine K. Hanson
Saturated Fat Intake Is Associated With Lung Function In Individuals With Airflow Obstruction: Results From Nhanes 2007⁻2012, Kasey Cornell, Morshed Alam, Elizabeth Lyden, Lisa Wood, Tricia D. Levan, Tara M. Nordgren, Kristina L. Bailey, Corrine K. Hanson
Journal Articles: Biostatistics
Nutritional status is a well-recognized prognostic indicator in chronic obstructive pulmonary disease (COPD); however, very little is known about the relationship between lung function and saturated fat intake. We used data from the cross-sectional National Health and Nutrition Examination Surveys (NHANES) to assess the relationship between saturated fatty acid (SFA) intake and lung function in the general US adult population. Adults in NHANES (2007⁻2012) with pre-bronchodilator spirometry measurements and dietary SFA intake were included. Primary outcomes were lung function including forced expiratory volume in one second (FEV₁)
Stretching Hiv Treatment: A Replication Study Of Task Shifting In South Africa, Baojiang Chen, Morshed Alam
Stretching Hiv Treatment: A Replication Study Of Task Shifting In South Africa, Baojiang Chen, Morshed Alam
Journal Articles: Biostatistics
The Streamlining Tasks & Roles to Expand Treatment and Care for HIV (STRETCH) program was developed to increase the reach of antiretroviral therapy (ART) for HIV/AIDS patients in Sub-Saharan Africa by training nurses to prescribe, initiate, and maintain ART. Fairall and colleagues conducted a cluster-randomized trial to determine the effects/impact of STRETCH on patient health outcomes in South Africa between 2008 and 2010. The purpose of our replication study is to evaluate Fairall and colleagues' findings. We conducted push button and pure replication studies and measurement and estimation analyses (MEA). Our MEA validates the original findings: (1) overall, time to …
