Global hotspots and trends in diabetic peripheral neuropathy research from 2011 to 2023

Abstract

Diabetic peripheral neuropathy (DPN) is a prevalent disease, and the relevant literature has been increasingly investigated over the past years. Consequently, it is imperative to conduct a scientific and comprehensive DPN research field bibliometric analysis. This study aims to summarize and visualize the literature distribution laws, the research hotspots, and the development trends in DPN using bibliometric methods. We searched all relevant documents published from 2011 to 2023 in the Web of Science Core Collection. Bibliometric analysis and network visualization were performed using VOSviewer, R-bibliometrix, and CiteSpace tools, focusing on countries, institutions, authors, journals, highly cited papers, references, and keywords. This study included a total of 2708 documents. The annual number of publications in the field has notably increased. China, the USA, and the UK take on critical significance in DPN research. The University of Manchester in the UK has the highest number of publications (109). Malik has the most publications (86). Tesfaye literature has been most frequently cited by scholars of DPN research. The Journal of Diabetes and its Complications and Frontiers in Endocrinology have the most publications (45 each). Diabetes Care stands out with the highest impact factor (16.200), number of citations (2516), and H-index (27) among the number of publications top 10 journals. The paper “Colloca, L. et al Neuropathic pain. Nature Reviews Disease Primers. 2017, 3 (1):1–19” has the highest number of citations (1224 times). The most critical co-cited reference is “Tesfaye S, 2010, DIABETES CARE, V33, P2285” (cited 408 times). Keywords like “type 2 diabetes,” “diagnosis,” “association,” “retinopathy,” “risk factors,” “progression,” “corneal confocal microscopy,” “nephropathy,” “balance,” “microvascular complications,” “inflammation,” “disease,” and “insulin resistance” represent the recent research hotspots. The development, research hotspots, and future trends of the global DPN domain from 2011 to 2023 were summarized and visualized in this study. This study can present more insights into the general situation of DPN research and provide a useful reference for clinical decision-making and directions of subsequent research.
