Systematic Reviews

Introduction to Systematic Reviews

Systematic Reviews (SRs) aim to gather and assess all relevant studies—whether published or not—that address a specific research question. They follow clear, structured methods to reduce bias and ensure the process is transparent, so others can replicate and verify the findings.

High quality systematic reviews seek to:

  • Identify all relevant published and unpublished evidence
  • Select studies or reports for inclusion
  • Assess the quality of each study or report
  • Synthesise the findings from individual studies or reports in an unbiased way
  • Interpret the findings and present a balanced and impartial summary of the findings with due consideration of any flaws in the evidence."
