Epidemiology Of Study Design - StatPearls - NCBI Bookshelf
In epidemiology, researchers are interested in measuring or assessing the relationship of exposure with a disease or an outcome. As a first step, they define the hypothesis based on the research question and then decide which study design will be best suited to answer that question.
Clinical research study designs: The essentials - PMC
From an epidemiological standpoint, there are two major types of clinical study designs, observational and experimental. 3 Observational studies are hypothesis‐generatingstudies, and they can be further divided into descriptive and analytic.
Experimentalepidemiology uses an experimentalmodel to confirm a causal relationship suggested by observational studies. Learning Objectives Summarize the purpose of experimental epidemiology and the three case types: randomized control, field and community trial
Observational and interventional study design types; an overview
Within primary research there are observationalstudies and interventional studies. Observational studies, also called epidemiological studies, are those where the investigator is not acting upon study participants, but instead observing natural relationships between factors and outcomes.
Study Designs – Epidemiology - Virginia Tech
Figure 3.3 describes five types of observationalstudy designs: case series, ecologic studies, cross-sectional studies, case-control studies, and cohort studies. From left to right, the designs are listed in order of the strength of their evidence (weakest to strongest).

ObservationalStudies. In observational (non-experimental) studies, investigators observe individuals without experimental manipulation or intervention. There is an inadequacy about the term “observational study” because the outcome variable of an experiment could also be observed.

In this chapter we review common epidemiologicstudy designs including (i) cohort studies (general prospective cohort studies, perinatal/birth cohorts, twin studies, and high-risk cohort studies); (ii) case–control studies, including nested case–control studies within larger cohorts; (iii) cross-sectional studies; (iv) quasi-experimental designs...

ObservationalStudies. Case-Control Studies. Case-control studies are used to determine the degree of associations between various risk factors and outcomes. The factors that affect the risk of a disease are called exposures. Case-control studies can help identify beneficial or harmful exposures.
