Identifying causative factors involves several epidemiological methods:
1. Observational Studies: These include cohort studies, case-control studies, and cross-sectional studies. 2. Experimental Studies: Randomized controlled trials are used to establish causality. 3. Statistical Analysis: Methods like multivariate analysis help in identifying potential causative factors from collected data. 4. Biological Plausibility: Understanding the biological mechanisms that link a factor to a disease.
