Abstract

Purpose: To identify and characterize the 100 most-cited articles in the field of transient elastography.

Methods: The top-cited articles focusing on transient elastography from 1999 to 2017 were retrieved from Science Citation Index Expanded (SCI-E) database. The most prolific article, journal, country and continent, top-cited article in different period, international collaboration, cocitation analysis of journal were retrieved and analyzed in this article. Bibexcel 2016, Microsoft Excel 2010, and VOSviewer 1.6.5 were used to analyze bibliometric records we downloaded.

Results: The 100 most-cited articles were published between 2003 and 2015. The total citations ranged from 54 to 1376 (mean, 167.52 ± 208.46; median, 89.5) and the annual citations ranged from 4.91 to 98.24 (mean, 17.21±15.68; median, 12.1). The top-cited article was published in Gastroenterology in 2005 by Castera L. et al. (n=1376). The most-cited articles in 2003-2007 (n=1380), 2008-2012 (n=599) and 2013-2017 (n=159) were located. All of the most-cited articles in three periods were focusing on the topic of noninvasive assessment of liver fibrosis. The most prolific author was de Ledinghen V. (n=21) and France (n=43) was the leading country. The most productive journal was Journal of Hepatology (n=20). The major article type was original research article.

Conclusions: We undertook efforts to provide an insight into the features and evolvement of the most-cited articles in the field of transient elastography. For transient elastography, as a noninvasive assessment of liver fibrosis, its use in the evaluation of liver fibrosis is gradually mature and shows great advantages. Moreover, the field of transient elastography is in a stage of rapid development.

Journal cocitation analysis. Journals with a minimum of 20 citations were included. The size of the circles represents the total link strength of the journal, and the width of line shows the link strength between two journals. Only the link strength more than 100 will be displayed. The different colors represent different clusters.

Visualization of international collaboration between countries; the size of the circles represents the collaboration degree, and the width of line illustrates the strength. If a country did not cooperate with other countries to accomplish one of the 100 cited-most articles, it will not be shown in the figure.

Conditions of transient elastography's research in different countries over time. The number of most-cited articles in each country in three periods which are represented by three colors: the period from 2003 to 2007 (blue), the period from 2008 to 2012 (red), and the period from 2013 to 2017 (green). If no article was on the list of the 100 most-cited articles from a particular country in a certain period, there will be no bar referring to that country shown in the period.
