Top 100 Most-Cited Articles on Spontaneous Intracerebral Hemorrhage: A Bibliometric Analysis

Abstract Background A bibliometric uses the citation count of an article to determine its impact on the clinical world. There is a paucity of literature concerning top article citations on spontaneous intracerebral hemorrhage (ICH). The main objective of this investigation was to bridge this gap and to provide understanding of the trends on the most influential articles written on this subject. Methods Scopus Library database was searched to determine the citations of all published spontaneous ICH articles. Articles that focused on other forms of ICH, such as trauma-related hemorrhages, sub-arachnoid hemorrhages, hemorrhages due to anti-coagulation, vascular malformations or cavernomas were excluded from our list. Our articles were divided into two groups; ‘Specific’ articles, that focused specifically on spontaneous ICH, and ‘Generalized’ articles that were about ICH in general, including spontaneous as well as other forms of ICH. We did not apply any time or study-type restriction in our search. The top 100 cited articles were selected and analyzed by 2 independent investigators. Results Broderick J was the author with most publications in the list (n=21). The largest subset of the spontaneous ICH articles was published in the 5-year periods from 1996 to 2000 and 2001 to 2005 (n=27 each). United States had the highest number of articles (n=49). The journal with the highest number of top 100 cited articles was Stroke with 39, followed by 16 in Neurology. Conclusion In conclusion, our study identifies the trends related to the subject of spontaneous intracerebral hemorrhage by analyzing the citation frequency of the most cited articles in the field.
