Landmark publications on Sudden Infant Death Syndrome: A bibliometrics analysis

Sudden infant death syndrome (SIDS) is a poorly understood disorder, and its pathophysiology and risk factors remain unclear. Research in the area is the key to combating the pervasive prevalence of this fatal disorder. We sought to identify the top 50 articles concerning SIDS and study their bibliometric characteristics to gain an insight into the research trends in this area. Using the Scopus database, two independent reviewers conducted a literature search using a prespecified search string. Results were arranged according to the citation count, and the top 50 relevant articles were selected. No time restrictions were set, and all types of articles were included. A detailed analysis was carried out to identify the trends and characteristics of the top 50 articles. The top 50 articles were published between 1972 and 2011, with the most productive 5-year interval being 1991-1995. These 50 papers accumulated a total of 13,703 citations (median = 236 citations per paper). Among these, about 9% were self-citations. The citations received by these core papers seemed to decline post-2009. The top 50 articles were published in 21 different journals, with Pediatrics contributing the most (n = 15). US authors were listed for 60% of the articles (n = 30). None of the articles originated from Asian authors. Our manuscript highlights the characteristics of impactful articles on SIDS - and this can act as a directive for researchers aiming to publish on this topic. Bibliometric parameters suggest a decreasing research interest in the fi eld of SIDS, which is concerning, and efforts should be made to promote research. Furthermore, the lack of influential research from Asian authors is also troubling. Funding should preferably be directed toward Asian researchers to bridge the gap in knowledge.
