How Do Epidemiologists Identify Causal Factors?

Epidemiologists use various research methods to identify causal factors:
- Observational Studies: These include cohort, case-control, and cross-sectional studies that observe the relationship between exposures and outcomes in natural settings.
- Experimental Studies: Randomized controlled trials (RCTs) that manipulate exposure to determine its effect on outcomes.
- Statistical Models: Used to control for confounding variables and to establish associations between exposures and outcomes.
