Systematic Review
Definition
A systematic review synthesizes existing research on a specific question using predefined methods to minimize bias. They may or may not include meta-analysis.
Correct Scientific Usage
Systematic reviews follow transparent protocols for study selection, evaluation, and synthesis. They are considered the gold standard for summarizing evidence.
Common Misunderstandings
All reviews are assumed to be systematic, but many are not. The systematic methodology of a systematic review is what distinguishes it from traditional literature reviews.
Why It Matters
Systematic reviews provide the most comprehensive and unbiased summary of available evidence, making them extremely valuable for informed decision-making.
