Systematic review:
1. Methodology: Systematic reviews follow a structured and rigorous methodology to identify, select, and critically appraise relevant studies on a specific research question.
2. Inclusion criteria: Systematic reviews have predefined inclusion and exclusion criteria for selecting studies, which helps ensure that only high-quality and relevant studies are included in the review.
3. Transparency: Systematic reviews are transparent in their methods and reporting, allowing readers to understand how the review was conducted and make judgments about the validity and reliability of the findings.
4. Bias reduction: Systematic reviews aim to minimize bias by using systematic and transparent methods for selecting and synthesizing evidence, which helps ensure that the findings are reliable and unbiased.
Narrative review:
1. Methodology: Narrative reviews do not follow a structured methodology and are often based on the author's expertise and opinion rather than a systematic search and appraisal of the literature.
2. Inclusion criteria: Narrative reviews may not have predefined inclusion and exclusion criteria for selecting studies, which can lead to a biased selection of studies and potentially unreliable conclusions.
3. Transparency: Narrative reviews may not be as transparent in their methods and reporting as systematic reviews, making it difficult for readers to assess the validity and reliability of the findings.
4. Bias reduction: Narrative reviews are more prone to bias due to the lack of a systematic and transparent approach to selecting and synthesizing evidence, which can lead to unreliable and biased conclusions.

Systematic Review
- Purpose: To provide a comprehensive and objective assessment of all available research evidence on a specific topic.
- Method:
- Systematic search of databases and other sources for relevant studies
- Rigorous selection criteria to include only high-quality studies
- Quantitative analysis of data (e.g., meta-analysis) to synthesize findings across studies
- Advantages:
- Reduces bias by including all relevant studies
- Provides a more comprehensive and reliable assessment of the evidence
- Allows for statistical pooling of data to provide more precise estimates
- Disadvantages:
- Can be time-consuming and resource-intensive
- May not capture all relevant evidence (e.g., gray literature)
Narrative Review
- Purpose: To present a subjective and qualitative overview of the existing literature on a topic.
- Method:
- Non-systematic search for relevant studies
- Selection criteria may be less rigorous
- Qualitative synthesis of findings, often based on the author's interpretation and expertise
- Advantages:
- Can provide a more nuanced and in-depth discussion of the topic
- Can include both qualitative and quantitative studies
- More flexible and can adapt to emerging evidence
- Disadvantages:
- Can be biased by the author's perspective
- May not be as comprehensive as a systematic review
- Difficult to draw firm conclusions due to the lack of quantitative analysis
Key Differences
| Feature | Systematic Review | Narrative Review |
|---|---|---|
| Purpose | Comprehensive objective assessment | Subjective qualitative overview |
| Method | Systematic search and quantitative analysis | Non-systematic search and qualitative synthesis |
| Bias | Minimized by including all relevant studies | Potentially biased by author's perspective |
| Comprehensiveness | More comprehensive | Less comprehensive |
| Reliability | More reliable | Less reliable |
| Statistical analysis | Meta-analysis or other quantitative methods | No formal statistical analysis |
