Evidence mapping is a new type of comprehensive evidence research method that systematically collects, evaluates, and synthesizes existing evidence to clarify research status and gaps, thereby promoting scientific research and decision-making. After nearly 20 years of development, the methodology of evidence mapping has been continuously improved, and has gained wide attention and recognition from the international community. China has paid much attention to evidence mapping at an early stage, but there are relatively few theoretical and practical researches, and the concept definition is inconsistent. This paper introduces the methodology of evidence mapping production and reporting for researchers to use for reference, with a view to further promoting the research and development of evidence mapping in China.
