Several challenges can complicate the review of epidemiological data:
- Incomplete Data: Missing data can bias results and reduce the validity of findings. - Data Heterogeneity: Variations in data collection methods across different sources can make it difficult to combine datasets. - Confounding Variables: Factors that can distort the perceived relationship between the primary variables of interest. - Ethical and Privacy Concerns: Ensuring that data use complies with ethical standards and privacy laws, such as the Health Insurance Portability and Accountability Act (HIPAA).
