Bibliometric analysis of studies involved in latent tuberculosis infection (LTBI). In the Web of Science database, the search formula “{[TS = (tuberculosis)] OR [TS = (TB)]} AND {[TS = (latent tuberculosis infection)] OR [TS = (LTBI)]}” was used to retrieve and export the full record results (n = 2724). In addition, CiteSpace 6.2.R2 (64-bit) Basic (https://citespace.podia.com) was used to perform citation-based visualization of the data derived from Web of Science, including: a the research progress map with three years as time slices, b literature clustering based on keywords, and c the distribution of clusters on the timeline.
