| Tóm tắt≠ | A systematic literature review (SLR) is a structured, reproducible method for identifying, appraising, and synthesizing all relevant studies on a research question. Unlike a narrative review, it follows an explicit, pre-specified protocol — from database search strings through inclusion criteria to data extraction — so that the process is transparent, auditable, and replicable by other researchers. It is widely used in medicine, education, software engineering, and the social sciences to produce the most comprehensive possible evidence base on a topic. | An umbrella review is a systematic synthesis of multiple systematic reviews addressing overlapping or related research questions, typically on the same topic or intervention. Also called a 'review of reviews' or 'overview of reviews,' umbrella reviews consolidate evidence when two or more high-quality systematic reviews exist on the same clinical question. Grant and Booth (2009) formally categorized this methodology; Shea et al. (2017) developed AMSTAR-2, the critical appraisal tool for assessing the quality of included reviews. Umbrella reviews are essential when numerous systematic reviews produce conflicting conclusions, when rapid synthesis of evidence is needed for policy or clinical guidance, or when evidence has accumulated faster than any single systematic review can capture. |
