Figure 2 Analysis of the quantity and research trends on transcranial magnetic stimulation-based treatment of addiction from 2001 to 2023. A: The annual number of papers on transcranial magnetic stimulation (TMS)-based treatment of addiction published from 2001 to 2023 was obtained from Web of Science data; B: The proportion of basic and clinical research articles on TMS-based treatment of addiction published from 2001 to 2023; C: Analysis of publication numbers and growth trends for the leading 10 countries/regions in TMS-based addiction treatment, sourced from a bibliometric online platform; D: A bar graph illustrating the total citations from 190 retrieved articles across all countries. This figure displays the top 10 countries ranked by total citation count. Each bar corresponds to a country, with its length directly proportional to the total citation count.

Figure 3 Map of national/regional and institutional cooperation networks in studying transcranial magnetic stimulation-based treatment of addiction. A: Collaborations among 27 countries/regions in studying transcranial magnetic stimulation (TMS)-based treatment of addiction; B: Collaborative network map illustrating institutions engaged in researching TMS-based addiction treatments. The circles represent different countries/regions and institutions. Circle size denotes the number of published articles, while link thickness reflects the level of collaboration.

Figure 4 Collaborative network of authors in the field of transcranial magnetic stimulation-based treatment of addiction. This figure displays the top 10 authors with more than five publications. Circles symbolize authors, with links denoting collaborative relationships. There is a positive correlation between font size and the number of published papers.

Figure 5 Reference co-citation network analysis of publications on transcranial magnetic stimulation for addiction treatment, spanning 2001 to 2023. A: CiteSpace co-citation map of 6607 references related to transcranial magnetic stimulation (TMS)-based treatment of addiction. Each node symbolizes a reference. Node size correlates positively with citation frequency, while links between nodes indicate shared references within the same article. Nodes with a deeper red hue indicate papers with high citation frequency in recent years, whereas nodes with a deeper purple hue signify references cited more frequently in earlier years. The top 10 most cited publications are listed with their first author and year of publication; B: The 25 most influential references with significant citation bursts related to TMS-based addiction treatment, spanning publications from 2001 to 2023. The blue bars indicate the period in which the reference has been published, and the red bars represent bursts of citation frequency.

Figure 6 Analysis of the clustered network of publications in on transcranial magnetic stimulation for addiction treatment, covering the period from 2001 to 2023. A: A CiteSpace visual analysis of the co-cited literature clustering network. This figure displays the ten largest citation clusters; B: Timeline visualization of co-cited references concerning transcranial magnetic stimulation-based addiction treatment. Clusters are depicted by horizontal lines, with smaller label numbers indicating larger clusters. Node size represents co-citation frequency, while links denote co-citation relationships. Node and line colors indicate the citing years.

Figure 7 Analysis of keywords and burst detection of publications on transcranial magnetic stimulation-based treatment of addiction, published from 2001 to 2023. A: Word cloud illustrating the 100 most frequent keywords from research on transcranial magnetic stimulation-based addiction treatment; B: The 15 keywords with the most significant citation bursts, arranged by the year they began. Keywords marked in red bars indicate a sudden increase in using frequency during the corresponding period, and the blue color represents a relatively unpopular period.
