A systematic review is not the only type of review. Grant and Booth (2009) identified 14 different types of reviews:

• Critical review
• Literature review
• Mapping review/systematic map
• Meta-analysis
• Mixed studies review/mixed methods review
• Overview
• Qualitative systematic review/qualitative evidence synthesis
• Rapid review
• Scoping review
• State-of-the-art review
• Systematic review
• Systematic search and review
• Systematized review
• Umbrella review

Literature review:

• can be single-authored
• can be a broad topic or a specific question
• does not specify source of literature (i.e., databases searched)
• does not include reproducible search strategies
• does not have specific study selection criteria
• does not formally assess study quality
• may be influenced by the reviewer's theories, needs, and beliefs
• is narrative

Rapid review:

• is conducted with time constraints
• uses simplified systematic review methods
• includes time-limited formal assessment of study quality
• is narrative and tabular

Scoping review:

• assesses size and scope of available literature on certain topic
• limits literature searching by time and scope constraints
• does not formally assess study quality

Umbrella review:

• is a review of reviews
• compiles evidence from multiple reviews into one document
