Top 100 Most Cited Neurologic and Neurosurgical Articles on COVID-19: A Bibliometric Analysis

Abstract

ObjectiveWith the exponential growth of literature on coronavirus disease 2019 (COVID-19), we aimed to identify and characterize the 100 most cited COVID-19–related articles in neurology and neurosurgery.MethodsIn March 2021, we performed a title-specific search of the Scopus database using (“neurology” or “neurologic” or “neurosurgery” or “neurosurgical”) and “COVID” as our search query term without date restrictions. The top 100 most cited English-language articles were obtained and reviewed.ResultsOur search yielded 9648 articles published from December 2019 to March 2021. Bibliometric analysis of the top 100 articles found that the most cited article had a citation count of 1741 and was the first to report on the detailed neurologic manifestations of the disease; Neurology had the most number of publications; the majority of the primary authors were neurologists, but 35% were from nonneuroscience specialties; the United States, Italy, the United Kingdom, China, and Germany were the top contributors, with a combined total of 77%; most of the publications were correspondence or editorial articles; and most articles discussed the neurologic manifestations and complications of patients with COVID-19.ConclusionsThis study identified the top 100 most cited neurologic or neurosurgical COVID-19–related articles published to date. This list can be used to identify high-impact studies that will help health care practitioners in clinical decision making and researchers in navigating key areas of study and guiding future research.
