N 1. What is the fundamental difference between the method you have chosen (either the case-control or cohort method) and the randomized controlled trial?The fundamental difference between case-control methods and randomized controlled trials is that in case control methods individuals with similar interests are compared to individuals without similar interests (Curly Cupp, 2020). Individuals are observed and the study is used to estimate odds, no intervention is attempted. While as for the randomized controlled trial methods interventions are controlled and individuals randomly get placed in the control or intervention group (Curly Cupp, 2020).What are the advantages and disadvantages of the study method you chose (case-control or cohort study)?Every study design has its’ advantages and disadvantages. The case-control study has the ability to determine risk factors present in each group and correlate the relationship between interests (Case Control – Study Design 101, 2019). The study can be inexpensive and gives the opportunity to study rare diseases. However, the disadvantage of the case control methods is the increased risk of bias, unknown variables, and inaccuracy of information on exposure (Curly Cupp, 2020).What are the characteristics of a correlational study?Correlational studies are also known as ecological studies and aid in determining risk factors, prevalence, and exposure to diseases or issues in a population (Curly Cupp, 2020). The study explores relationships among variables and the researcher does not have control. Populations are studied using correlation studies and can only report if a correlation exists (Curly Cupp, 2020).Where does the method you chose (case-control or cohort study) fall on the research pyramid? What does where it is on the research pyramid mean?The case-control study falls under the unfiltered information of the evidence pyramid, which is towards the bottom. The pyramid is used as an organization for different types of evidenced-based research, the bottom of the pyramid shows an increase in evidence but a decrease in quality (Academic Guides: Evidence-Based Research: Levels of Evidence Pyramid, 2021). When researching, it’s always recommended to look for the highest level of evidence-based on the clinical question.
