What are the Key Research Methods in Epidemiology?
Epidemiologists use various research methods to investigate health-related events. The primary methods include observational studies, experimental studies, and analytical studies. Observational studies, such as cohort studies and case-control studies, provide insights into the natural progression of diseases. Experimental studies, including randomized controlled trials, are used to test hypotheses and interventions. Analytical studies assess the relationship between exposures and outcomes.
