Fig. 7From: Emerging trends and focus of human gastrointestinal microbiome research from 2010–2021: a visualized studyThe Keyword clustering knowledge map of the human gastrointestinal microbiome during 2010–2021. CiteSpace uses Log-likelihood rate (LLR) to cluster closely related keywords. Different patterns represent a cluster. Tag # was assigned to the cluster, and the smaller the number is, the more keywords are in the cluster. The size of each cluster, the Silhouette value, and the mean publication year of articles in that cluster are shown in the upper right corner [28]Back to article page
