What are the Different Types of Epidemiological Studies?
Epidemiological studies can be broadly classified into observational and experimental.
- Observational Studies: These include cohort studies, case-control studies, and cross-sectional studies. They observe the natural occurrence of diseases and their determinants in populations. - Experimental Studies: These include randomized controlled trials (RCTs) and field trials. They involve intervention by the researcher to determine the effect of a treatment or preventive measure.
