Visualizing the landscape of appendiceal tumor research after 2010: A bibliometric study

Figure 1 Publications screening flowchart. A total of 1472 publications were included according to the filtering strategy and inclusion criteria. Then, 692 publications were excluded according to exclusion criteria of letters, editorial materials, corrections, books, data sets, proceedings papers, retractions, and retracted publications. In total, 780 publications were retrieved. WoSCC: Web of Science Core Collection.

Figure 2 Annual output of appendiceal tumor research. Each point represents the number of papers published in the respective year.

Figure 3 Number of publications by different total citations. The bars of different length correspond to the number of papers in different total citation ranges.

Figure 4 Geographical distribution and visualization of countries/regions. A: Intensity of the blue color represents publication count and thickness of the line represents cooperation intensity; B: Node size represents publication count, and link size indicates cooperation intensity.

Figure 5 Collaboration network of institutions. Node size represents publication count, and link size indicates cooperation intensity. The time of contributions is presented by the brightness of the color.
