Mapping the global research landscape on insulin resistance: Visualization and bibliometric analysis

Figure 1 Annual growth of publications on insulin resistance research the last two decades (2002-2021). Source: Own elaboration, based on Scopus; this figure created using EXCEL version 2013.

Figure 2 Map of visualization of worldwide research collaboration network. Countries with short distances and extensive connecting lines had a significant research collaboration. This collaborative map was built when each country had at least 100 articles. Source: Own elaboration, based on Scopus database; figure created using VOSviewer Software.

Figure 3 Network visualization map of terms in the titles/abstracts with a minimum occurrence of 300 or more. Of the 250809 terms in this field, 456 achieved this threshold, were grouped into two clusters, and colored differently. Each cluster represents a general research theme present in the retrieved documents. Source: Own elaboration, based on Scopus database; figure created using VOSviewer Software. LDL-C: Low-density lipoprotein cholesterol; HDL: High-density lipoprotein; IGT: Impaired glucose tolerance; OGTT: Oral glucose tolerance test; BMI: Body mass index; HFD: High fat diet; IRS: Insulin receptor substrate; CRP: C-reactive protein; HOMA-IR: Homeostatic Model Assessment of Insulin Resistance.
