Using Previous Longitudinal Group Randomized Rural Weight Loss Study Data to Design A Prospective Rural Weight Loss Trial

Alexandra R Brown, Byron J Gajewski, Matthew S Mayo, Edward F Ellerbeck and Christie A Befort

Article Type: Original Article | Indexed Archive: Volume 11

Considerations must be taken when designing group-randomized trials due to the hierarchical structure of the data. Longitudinal group-randomized trials have an added layer of nesting adding more complexity to the study design. Simulation studies have been performed to compare the operating characteristics and validate statistical models for these hierarchical data structures, but many provide simulations from parametric distributions under set assumptions....

IFST2BR: An Interpretive Framework for Statistical Tests Aimed at Budding Biological Researchers

Shahad Dakhil Khalaf

Article Type: Research Article | Indexed Archive: Volume 10

A statistical test is a formal method used in data analysis to make inferences, identify relationships, and draw conclusions about a population based on sample data. Many emerging biological researchers face challenges in managing their statistical findings because they often lack clear guidelines or interpretive frameworks to help them navigate their research safely....

A Comparative Study of Probability Distribution Models for Number of Antenatal Visits

Ayodeji Isaac Akinjisola and Emmanuel Teju Jolayemi

Article Type: Original Research | Indexed Archive: Volume 10

There are several complications that arise as a result of lack or insufficient antenatal care received by pregnant women. Studies show that lack of education, poverty and several other factors give rise to low antenatal attendance in Nigeria and the consequences are grievous. This study was aimed at determining the factors that affect the frequency of antenatal visits in Nigeria....

Design of Inequality Models of Covid-19 Disease Incorporating Social Discriminants

Yisa Oluwatoyin Anthonio, Joseph Adekunle Akinyemi and Kamilu Rauf

Article Type: Original Article | Indexed Archive: Volume 10

Fatal disease like Coronavirus (COVID-19) is a contagious disease which causes death. In 2019 and 2020, millions of deaths were recorded as a result of its outbreak. The impact of the outbreak disrupted Economic and social activities globally. The spread across globe exposed existing social and health inequalities. Disparities in hygiene and level of awareness of the havoc the disease can cause had been the bane of public health interventions. To verify this claim, inequality of non-linear mathe...

Analyzing the Covariance Structure of Plasma Signaling Proteins in Relation to the Diagnosis of Dementia

Calvin Guan, Rhoda Au, Alvin Ang and Ashis Gangopadhyay

Article Type: Original Research | Indexed Archive: Volume 10

Numerous studies have shown that individuals with dementia have exhibited activation of inflammatory pathways in their brains. Typically, these studies use traditional and well-established regression methods for data analysis. In this paper, a new approach is introduced that utilizes the analysis of the covariance structure using methods related to the principal component analysis (PCA) theory. Eleven biomarkers related to neuroinflammation were used to determine the association with the onset o...

Fitting Birth and Death Queuing Models using Maximum Likelihood Estimation with Application to COVID-19 Pandemic in Sub-Saharan Africa

Nkemnole EB and Kuti OO

Article Type: Research Article | Indexed Archive: Volume 9

The COVID-19 pandemic has revealed facts about deficiencies in health resource planning of some countries having relatively high case count and death toll. The virus has undergone an observed increase of cases that led to a global pandemic. Many authors have developed different models for predicting or observing the current trend of COVID-19 pandemic. In this study, fitting birth and death models using maximum likelihood estimation (MLE) method with application to COVID-19 in sub-Sahara Africa i...

Hypothyroidism: A Small Clinical Trial Will Quickly Resolve the Combination Therapy Controversy

Timothy A Welborn, AO, PhD, FRCP, FRACP, MBBS and Satvinder S Dhaliwal, PhD, MSc, BSC

Article Type: Letter | Indexed Archive: Volume 8

Hypothyroidism is an extremely common condition. More than 100 million prescriptions for thyroxine (T4) are processed in the USA each year. T4 is the recommended treatment for hypothyroidism. But 5-15% of patients treated to target with T4 continue to have symptoms. Some of these patients respond dramatically to the addition of triiodothyronine (T3) as first reported 20 years ago....

A New Modified Liu Ridge-Type Estimator for the Linear Regression Model: Simulation and Application

Olasunkanmi J Oladapo, Abiola T Owolabi, Janet I Idowu and Kayode Ayinde

Article Type: Original Research | Indexed Archive: Volume 8

Several efforts have been made to solve the multicollinearity problem, which arises from correlated regressors in the linear regression model. This is because the Ordinary Least Squares (OLS) Estimator becomes inefficient in the presence of multicollinearity....

Development of a Novel Retrospective Instrument to Gauge the General Well-being Index and Lumbar Specific Disability Index Post Intervention in Lumbar Degenerative Disease

Song Ying Chong, MBBS, Mahmoud Danaee, PhD and Dharmendra Ganesan, FRCS

Article Type: Original Article | Indexed Archive: Volume 8

The clinical outcome data for patients who had a particular intervention for the lumbar degenerative disease is based on changes in symptomatology. This functional data had been acquired in a prospective manner using standard tools e.g., ODI, RMQ, SF-36 etc. Such data may be lacking in many facilities of developing countries due to various reasons....

Time Based Prediction of Breast Cancer Tumor Recurrence Using Machine Learning

Siddharth Raj Gupta

Article Type: Original Article | Indexed Archive: Volume 8

An in-depth study using the database from GLOBOCAN, CDC, and WHO health repository highlights the lethality of breast cancer, taking thousands of lives each year. Therefore, timely prediction of cancer can help patients to consult the doctor on time. In the past various studies have successfully predicted the nature of the tumor to be benign or malignant and if the breast cancer tumor will reoccur or not. However, no time-based models have been studied previously. With the help of Machine Learni...

Triple Negative Breast Cancer Prevalence in Indian Patients over a Decade: A Systematic Review

Suvobrata Sarkar and Murtaza Akhtar

Article Type: Systematic Review and Meta-analysis | Indexed Archive: Volume 8

Triple Negative Breast Cancer (TNBC) is an aggressive variant of breast cancer with penurious prognosis and limited therapeutic options. This subtype is characterised with higher incidence rate among the younger women, aggressive tumour behaviour, with early local recurrence and distant metastasis leading to poor outcomes. In India, majority of prevalence data of TNBC is hospital based from patient treated at tertiary care hospitals or centres ranging from 10% to 43% which is evident from the va...
