What are the Common Limitations in Epidemiological Studies?

Despite the rigorous methods employed, epidemiological studies have inherent limitations:
- Sample Size: Small sample sizes can lead to unreliable results and reduce the power of the study.
- Generalizability: Findings from a specific population may not be applicable to other groups.
- Causality: Establishing a causal relationship is often difficult due to the observational nature of many epidemiological studies.
