Types of Research: Systematic Reviews

Systematic Reviews

A systematic review is essentially a high-quality summary of existing research on a specific topic. It follows a rigorous and transparent methodology to identify, evaluate, and synthesize findings from multiple primary studies.

Here are some key features of a systematic review:

  • Focused question: It addresses a clearly defined research question, aiming to inform understanding and decision-making within a particular area.
  • Systematic search: Researchers employ a methodical approach to searching for relevant studies across various databases and sources, minimizing bias in selection.
  • Eligibility criteria: Pre-defined criteria are established to determine which studies are included in the review, ensuring they directly address the research question and meet quality standards.
  • Critical appraisal: The studies are carefully assessed for their strengths and weaknesses, including potential biases and methodological limitations.
  • Synthesis of findings: The results from the included studies are brought together and summarized in a clear and concise manner, often using tables or figures.
