Journal ArticleDOI
Joint longitudinal data analysis in detecting determinants of CD4 cell count change and adherence to highly active antiretroviral therapy at Felege Hiwot Teaching and Specialized Hospital, North-west Ethiopia (Amhara Region).
TL;DR: Joint model analysis was more parsimonious as compared to separate analysis, as it reduces type I error and subject-specific analysis improved its model fit, and the observed correlation between the outcomes that have emerged from the association of intercepts is validated.
Journal ArticleDOI
Quasi-Poisson versus negative binomial regression models in identifying factors affecting initial CD4 cell count change due to antiretroviral therapy administered to HIV-positive adults in North–West Ethiopia (Amhara region)
TL;DR: Adherence to antiretroviral therapy, initial CD4 cell count, household income, WHO stages, age, weight and owner of cell phone played a major role for the variation of CD 4 cell count in the authors' data.
Journal ArticleDOI
Community-perceived state of women empowerment in some rural areas of Limpopo Province South Africa
TL;DR: In this article, the perceived state of women empowerment in some rural areas of Makhado Municipality in South Africa was investigated, where a total of 5 924 people comprising children, youth, women, men and local leaders voluntarily participated in the study.
Journal ArticleDOI
Factors affecting first month adherence due to antiretroviral therapy among HIV-positive adults at Felege Hiwot Teaching and Specialized Hospital, north-western Ethiopia; a prospective study
TL;DR: Certain groups of patients who are at higher risk and who need counseling should be targeted and tailored for improvement of adherence to HAART among HIV positive adults.
Journal ArticleDOI
The analytic construction of D-optimal designs for the two-variable binary logistic regression model without interaction
TL;DR: In this article, Lopez-Fidalgo et al. proved algebraically the global D-optimality of the 3-point design for the special case in which the intercept parameter is equal to −1.5434.
