Why is Review Literature Important in Epidemiology?

Review literature is critical in epidemiology for several reasons:

- Evidence Synthesis: It helps in synthesizing evidence from multiple studies, providing a broader understanding of a health issue.
- Identifying Gaps: Reviews can identify gaps in existing research, highlighting areas that need further investigation.
- Guiding Policy: Reviews often inform public health policies and clinical guidelines by providing a consolidated view of evidence.
- Avoiding Redundancy: They prevent duplication of research efforts by summarizing existing findings.
