What are the Limitations of Epidemiological Evidence?
Epidemiological evidence has several limitations:
- Observational Nature: Many epidemiological studies are observational, which can make it challenging to establish causality. - Confounding Factors: Even with advanced statistical methods, it can be difficult to completely account for all confounding factors. - Bias: Despite efforts to minimize bias, it can still affect study results. - Data Quality: The quality of data can vary, affecting the reliability of the findings.
