Evidence synthesis is the process of systematically collecting, evaluating, and combining findings from multiple studies on a specific topic to draw more reliable and comprehensive conclusions. It aims to summarize the existing body of research to inform decision-making in fields such as healthcare, education, social policy, and environmental science. One type of example of are systematic reviews, among others.
Systematic Reviews
Rigorously structured reviews that follow a predefined protocol to minimize bias
Scoping Reviews
Broader reviews that map the key concepts and types of evidence available on a topic
Rapid Reviews
Streamlined form of review that quickly summarizes research findings
Narrative Reviews
Qualitative summaries of literature, often used when data are too diverse for statistical combination
Meta-Analysis
Statistical techniques that combine numerical results from multiple studies to produce a single estimate
Umbrella Reviews
Review of existing systematic reviews and meta-analyses on a topic
Basically, evidence synthesis enhances the clarity and strength of what is known by
identifying consistent findings, gaps, and contradictions across studies.
