สรุป	A systematic review is a structured, transparent synthesis of all available evidence addressing a specific research question. Unlike narrative reviews, systematic reviews employ comprehensive database searches, predefined selection criteria, quality assessment, and rigorous reporting (PRISMA guideline). The Cochrane Collaboration (founded 1992) established this methodology as the gold standard for evidence synthesis in healthcare and social sciences.	A narrative literature review is an interpretive synthesis of published research organized around themes, concepts, or historical progression rather than systematic search. Unlike systematic reviews, narrative reviews employ subjective study selection, do not require protocol registration, and prioritize depth of interpretation over exhaustive comprehensiveness. Narrative reviews are valuable for conceptual synthesis, exploring emerging fields with sparse literature, and providing historical context; they have been the traditional form of scholarly literature synthesis since the inception of academic journals.
