Thematic analysis of multiple sclerosis research by enhanced strategic diagram

Abstract

Recent interest in multiple sclerosis research warrants literature analysis to evaluate the current state of the discipline and new research domains. This bibliometric review summarised the research trends and analysed research areas in multiple sclerosis over the last decade. The documents containing the term ‘multiple sclerosis’ in the article title were retrieved from the Scopus database. We used Harzing’s Publish or Perish and VOSviewer for citation analysis and data visualisation, respectively. We found a total of 18,003 articles published in journals in the English language between 2012 and 2021. The emerging keywords identified utilising the enhanced strategic diagram were ‘covid-19’, ‘teriflunomide’, ‘clinical trial’, ‘microglia’, ‘b cells’, ‘myelin’, ‘brain’, ‘white matter’, ‘functional connectivity’, ‘pain’, ‘employment’, ‘health-related quality of life’, ‘meta-analysis’ and ‘comorbidity’. This study demonstrates the tremendous growth of multiple sclerosis literature worldwide, which is expected to grow more than double during the next decade especially in the identified emerging topics.

“…To better understand the knowledge framework and dynamic evolution of the DN field over the past two decades, four two-dimensional (2D) strategy diagrams were constructed. These diagrams offer a visual means of describing external and internal connections for a particular research field [ 18 , 19 ], with X and Y coordinates serving as the most critical indicators for summarizing these diagrams. Coordinate calculation methods have been described in prior reports [ 20 ].…”

Mapping Research Themes and Future Directions in Learning Style Detection Research: A Bibliometric and Content Analysis

“…The visualization from co-occurrence analysis maps how research topics are related, their popularity, and the clusters of topics that are created. Therefore, co-occurrence analysis can investigate the main themes and topics or crucial concepts of publications (Shafin et al, 2022). The cooccurrence analysis yields a network visualization in Figure 6, which reveals the presence of three distinct clusters of themes.…”
