a structured, comprehensive, and transparent method for identifying, evaluating, and synthesizing all available research on a specific question or topic. Unlike traditional narrative reviews, an SLR follows a predefined protocol to minimize bias and ensure reproducibility. It typically involves systematic searching of multiple databases, explicit inclusion and exclusion criteria, and critical appraisal of the evidence.
Abbreviation: SLR
Synonyms: Systematic Review
Example
A research team conducts a Systematic Literature Review (SLR) to evaluate the effectiveness of exercise programs for reducing knee pain in osteoarthritis.
