What is an evidence synthesis?

An evidence synthesis refers to the process of integrating findings from various studies to create a comprehensive understanding of a particular topic. This approach pools data from multiple sources, allowing researchers to identify patterns, draw conclusions, and generate insights that individual studies alone may not provide. By synthesizing evidence, it becomes possible to assess the overall effectiveness of interventions or treatments, inform clinical practice, and guide informed decision-making.

This process commonly includes systematic reviews and meta-analyses, which rigorously evaluate and combine findings, enhancing the reliability and applicability of the results. In contrast, conducting surveys focuses primarily on gathering new data rather than integrating existing research. A statistical analysis of a single study does not encompass the broader integration of multiple studies required to create a comprehensive perspective. Reviewing clinical guidelines involves summarizing best practices but does not inherently require the integration of diverse research findings to form a cohesive understanding. Thus, the correct definition of evidence synthesis highlights its role in creating a richer context through the combination of various research findings.
