Quantitative and qualitative assessment of Indian research yield in type 1 diabetes during 1996-2020

Background: Type 1 diabetes (T1D) is a well-researched disease globally. The Indian contribution to global T1D research is unknown. Objective: The aim of this study was to provide a comprehensive assessment of publication output of Indian authors in the field of T1D. Materials and Methods: Scopus database was used to retrieve Indian publications on T1D during 1996-2019. The extracted data included the number of publications, citation metrics, top productive organizations and authors, research collaborations, most cited papers, and active journals, and were analyzed using appropriate bibliometric indicators. Results: Globally, the USA leads the ranking, of about 100 countries which participated in T1D research, with 29.3% of publication share, followed by UK (11.4%), and Germany, Italy, and Australia (6.9%-5.0%). India contributed only 1.7% (513 publications) share of global output, registered annual growth of 26.3% and averaged 9.7 citations per paper (CPP). Only 21.6% of publications involved international collaboration and 15.7% received funding. The two most productive organizations were PGIMER, Chandigarh and AIIMS, New Delhi with 51 and 43 papers, respectively. Indian Journal of Endocrinology and Metabolism (42 papers) and International Journal of Diabetes in Developing Countries (24 papers) were the two leading Indian journals, which published research on this topic.
