Evidence syntheses

Evidence syntheses are comprehensive summaries that combine results from multiple research studies on a particular topic. They aim to provide a clear and reliable overview of what has been learned, identifying common findings, gaps, and the overall strength of the evidence. This process helps inform decisions by presenting the collective knowledge in a structured way, reducing uncertainty that comes from individual studies alone. Examples include systematic reviews and meta-analyses, which are used in healthcare, social sciences, and other fields to guide practice, policy, and further research.
