Systematic reviews definition

  • A systematic review is an overview of primary studies that used explicit and reproducible methods
  • A meta-analysis is a mathematical synthesis of the results of two or more primary studies that addressed the same hypothesis in the same way
  • Although meta-analysis can increase the precision of a result, it is important to ensure that the methods used for the review were valid and reliable
