How to Conduct High-Quality Systematic Review and Meta-analysis in Radiology and Interventional Radiology

Area of Science:

• Radiology and Interventional Radiology
• Evidence-Based Medicine
• Research Methodology

Background:

• Systematic reviews and meta-analyses are secondary research methods.
• They critically appraise and synthesize relevant studies.
• These methods are crucial for evidence-based practice.

Purpose of the Study:

• To elaborate key steps for conducting high-quality systematic reviews and meta-analyses.
• To guide readers in designing and executing such research.
• To enhance understanding and interpretation of secondary research in radiology.

Main Methods:

• Identification and critical appraisal of relevant studies.
• Systematic search across multiple databases.
• Statistical analysis for pooled estimates (meta-analysis) when feasible.

Main Results:

• Systematic reviews of high-quality studies rank highest in the evidence hierarchy.
• Meta-analysis provides pooled effect estimates.
• Not all systematic reviews can include a meta-analysis.

Conclusions:

• This article provides a framework for conducting robust systematic reviews and meta-analyses in radiology.
• It empowers researchers to design, conduct, and interpret secondary research effectively.
• Adherence to methodology ensures unbiased and reliable findings.
