Abstract: Objective：To conduct bibliometric analysis of evidence mapping(EM) research， in order to explore the current status of EM and provide reference for scholars to carry out related research. Methods： EMs were obtained by searching PubMed， EMBASE.com， Cochrane Library and Web of Science. Using VOSviewer 1.6.10 software to extract the authors， countries， institutions and keywords， and generate visual cooperation network maps for the country， perform cluster analysis for keywords. CiteSpace V software was used to analyze the relationship between high-yield authors and high-yield institutions and to generate a visual knowledge map. Results： A total of 112 EMs were included， the countries with the largest number of publications is the United States (50papers)， the institutions with the largest number of publications is Tufts University (11papers)， and 591 authors participated in the publication of the evidence map research， but the authors with more than 2 papers accounted for only 4.74%. The main institutions formed three research teams， and the main authors formed six cooperative groups， but there was less cooperation among the authors and institutions. There are four main themes of research. The main research topics are the public health of human beings such as obesity and nutrition， the clinical status of infants and young children， and the mental health of adolescents. Conclusion： There are fewer high-yielding authors， more participating groups， and insufficient cooperation between groups and institutions. Further cooperation is needed. There are not many research topics， and new research topics still need to be developed.
