Aim: to integrate several independent studies to determine cumulative impact of evidence. Involves the statistical analysis of two or more separate studies, generally performed to increase power and precision and to determine answers to questions not posed in the original studies. All meta-analyses should include a systematic search, but not all systematic reviews will include a meta-analysis.
Synonyms: none known, network meta-analysis is a subtype
Notes about Methodology
PRISMA is an international group of methodology experts dedicated to improving reporting quality of reviews. Most journals that accept systematic reviews will adhere to the PRISMA checklist for systematic reviews and will require a PRISMA flow diagram.
