Experimental Study Design and Intention to Treat Hepatitis C Virus (HCV) association with HIV Infection in Gay Men

The population for this research will comprise of persons enrolled in one out of five CPCRA (Community Programs for Clinical Research on AIDS) studies at sixteen CPCRA facilities across America. The five researches will take the form of four randomized clinical trials (RCTs) for antiretroviral (ARV) therapy strategies and one natural history analysis of ARV treatment-naive patients. During enrolment in the study, researchers will determine every participant's HCV serostatus. Past positive results for HCV antibody test will also be accepted. HCV serological examinations will be locally conducted at baseline in case of patients without recorded HCV antibody test results or those showing negative HCV antibody results from eleven years prior to randomization. The baseline characteristics outlined include ethnicity, gender, age, plasma HIV viral load, history of IDU (injection drug use), CD4+ count, ARV therapy status (experienced or naive), and history of sexual contact with persons of the same sex. Multivariate and univariate logistic regression will be conducted for identifying baseline covariates linked to HCV infection prevalence at baseline (Bradshaw, Matthews & Danta, 2013; Schmidt et al., 2014).

Specific Advantages of Randomization Study

In RCTs,...

Control groups receive no or usual treatment; the measure of their outcome, or deviation of measure from baseline (i.e. starting point), is compared to intervention group outcome measure (Gupta, 2011). The practice of randomization ensures the absence of systematic differences in unknown and known factors capable of affecting outcome, among intervention groups. A blinding design guarantees the inability of preconceived investigator and subject views to systematically bias outcome assessment. Intention-to-treat (ITT) analysis has random allocation benefits, which might be lost if subjects were excluded from the analysis by means of, say, withdrawal or a need to make changes to intervention, owing to unforeseen circumstances.
Bias minimization is one aim of randomized studies. Allocation bias is said to occur when a difference arises between measured and true effect of treatment, due to control or intervention group participant selection methods. In RCT, after subjects are enrolled into a research, they are randomized to either of two groups: control or intervention. Randomization ensures characteristics, which may impact the link between outcome measures and the intervention, are almost equal across different study arms, thereby minimizing…

Pedagogic Model for Teaching of Technology to Special Education Students Almost thirty years ago, the American federal government passed an act mandating the availability of a free and appropriate public education for all handicapped children. In 1990, this act was updated and reformed as the Individuals with Disabilities Education Act, which itself was reformed in 1997. At each step, the goal was to make education more equitable and more accessible to

Eveland's research design is quasi-experimental. The sample populations for the experiment are not randomly selected. There is structure to the experiment with more than one form of measurement during the research process. Quasi-experimental design includes multiple groups and multiple waves of measurement. While there were not a significant number of groups in the experiment, there was more than one. At more than one point in the experiment, measurements were
