A systematic review is distinguished from other types of literature reviews primarily by its rigorous and structured methodology, which ensures that the review process is replicable. This approach typically involves a predefined protocol that outlines the criteria for including studies, the specific research questions being addressed, the systematic method for searching and selecting studies, and formal mechanisms for data extraction and analysis.

This structured approach not only minimizes bias but also allows for comprehensive and methodical aggregation of data from different studies, leading to more reliable conclusions. As a result, systematic reviews often feature detailed assessments of the quality of the studies included, integration of quantitative data, and an analysis of the results that is transparent and systematic.

In contrast, other literature reviews may lack this level of rigor, relying instead on more narrative summaries that may not follow a clear method or may selectively include studies based on less systematic criteria. Additionally, they might not be as focused on replicability since they do not follow a strict protocol.
