Interdisciplinary perspectives on diabetes and microcirculatory dysfunction: A global bibliometric analysis

Figure 1 Systematic search and selection flowchart. This flowchart delineates the systematic process adopted in our study, divided into three sequential stages: Identification, purification, and bibliometric analysis and visualization. The identification stage involved a comprehensive search of original articles written in English from inception until December 31, 2023, using the search criteria (TS = (diabetes)) AND (TS = (microcirculation) OR TS = (microvascular)). This search yielded 11357 and 9042 publications from Web of Science Core Collection (WoSCC) and PubMed, respectively. During the purification stage, 6297 duplicate entries were removed from the PubMed dataset. Subsequently, two independent researchers scrutinized the remaining studies, excluding 936 and 280 studies from WoSCC and PubMed, respectively, that failed to meet predefined inclusion criteria. In the bibliometric analysis and visualization stage, the remaining 12886 original articles underwent detailed bibliometric analysis, encompassing aspects such as annual publication volumes, contributing countries/regions, institutions, journals, authors, keywords, and citation metrics. Additionally, a focused bibliometric exploration involving the search terms (TS = (COVID) OR TS = (COVID-19) OR TS = (corona virus disease 2019) OR TS = (novel coronavirus) OR TS = (SARS-Cov-2)) identified 44 relevant articles examining the intersections between diabetes, microcirculation, and COVID-19. Arrows within the flowchart indicate the sequential progression of the research process.
