Global trends and emerging topics related to triglyceride-glucose index: A bibliometric analysis and visualization...

The triglyceride-glucose (TyG) index is a crucial marker of insulin resistance, as evidenced by numerous studies related to metabolic diseases. This bibliometric analysis investigates research trends associated with the TyG index over the past 24 years. We collected data on TyG index publications from January 1, 2000, to January 7, 2024, using the Web of Science database. Analysis was conducted utilizing VOSviewer, Scimago Graphica, and CiteSpace to evaluate publication metrics, citations, countries, institutions, authors, journals, and keywords. A total of 1163 publications from 354 journals authored by 6149 researchers across 60 countries were analyzed. China emerged as the leading contributor, with 654 publications (56.23%). Capital Medical University was the most productive institution, and Wu Shouling was the top author. Cardiovascular Diabetology was identified as the most influential journal. Key emerging research directions include the role of the TyG index as a representative marker for insulin resistance, particularly concerning insulin sensitivity; its association with body mass index and hyperuricemia; and its diagnostic and prognostic value in nonalcoholic fatty liver disease and cardiovascular conditions such as acute coronary syndrome, carotid plaque, and hypertension. Current trends favor cohort studies predominantly involving adult populations. Overall, China leads TyG index research, focusing on its connections to insulin sensitivity, body mass index, and hyperuricemia, while the index's diagnostic and prognostic significance for nonalcoholic fatty liver disease and cardiovascular diseases represents an expanding research frontier.
