Systematic Review: 1. Synthesis

What is Synthesis?

 

 

Synthesis is a stage in the systematic review process where extracted data are pooled together and evaluated.

It is one of the most important stages of the systematic review process, as it determines the outcomes of the review.

 

 

There are two commonly accepted methods of synthesis in systematic reviews:

 

  • Quantitative data synthesis
  • Qualitative data synthesis

This division is not absolute, and even if you are conducting a quantitative systematic review, aspects of qualitative data synthesis are relevant in explaining why studies have been excluded differ from the findings of the meta-analysis.
