Systematic review meta-analysis protocol preparation and registration - A narrative review

Area of Science:

• Medical Research
• Evidence Synthesis

Background:

• Systematic reviews and meta-analyses (SRMAs) are crucial for informed decision-making, especially when dealing with conflicting research findings.
• SRMAs help identify heterogeneity sources, reduce subjectivity, and uncover knowledge gaps.

Purpose of the Study:

• This review focuses on the preparation and registration of systematic review and meta-analysis protocols.
• To highlight the importance of a well-defined protocol as a roadmap for SRMA research.

Main Methods:

• This is a narrative review.
• Focuses on the essential components of an SRMA protocol, including rationale, hypothesis, aims, and methodology.
• Emphasizes the necessity of protocol registration for transparency and efficiency.

Main Results:

• A well-written protocol minimizes bias, ensuring consistency in data collection, synthesis, and interpretation.
• Detailed protocols improve overall research quality and reliability.
• Public registration of protocols prevents resource wastage and duplication of efforts.

Conclusions:

• A robust SRMA protocol is essential for high-quality, reliable systematic reviews and meta-analyses.
• Protocol registration enhances research transparency, efficiency, and publication prospects.
