INTRODUCTION

The World Journal of Clinical Cases started out publishing high-quality peer-reviewed articles since 2013[1]. In this letter I would like to present a short summary of the performance of the journal in the past 5 years. A scientometric analysis was performed using the metadata of the articles published in the journal and indexed in Web of Science and Reference Citation Analysis[2] database over the past 5 years (2017-2021). Visualisation of the data was made using CiteSpace software[3].

Publication volume

The journal published 2792 articles between 2017 and 2021. The journal experienced three times growth in the number of publications with 12 issues in 2017 covering 452 pages in Volume 5 to 36 issues in 2021 covering 11508 pages in Volume 9. Similarly, the number of published articles rose from 71 in 2017 to 1296 in 2021 as shown in Figure 1.

Institutional network

Of the 2792 analysed articles, the top contributors were from Zhejiang University (143), Capital Medical University (129), China Medical University (99), Sichuan University (91), and Jilin University (82).

Country network

The People’s Republic of China contributed to 71% (1982) of the total publications in the past 5 years, followed by South Korea (160), United States (127), Japan (111), and Italy (74).

Cited references

In order to analyse the self-citation policy, analysis was made on the journals of the cited references from the included publications in the past 5 years. A total of 731 journals were cited in the 31774 references analysed. The top cited journals were New England Journal of Medicine (622), Lancet (538), World Journal of Gastroenterology (518), Medicine (460), and PLOS One (416). This proves that the journal was adherent to the self-citation policy with only 122 self-citations, which account for 0.3% of the total references analysed.

Keyword cluster analysis

On analysing the keywords of the included articles, clustering of the keywords was made to represent the subject of the included articles. The top clusters in the included articles were #0 case report, #1 colorectal cancer, #2 inflammatory bowel disease, #3 hepatocellular carcinoma, #4 neoadjuvant chemoradiotherapy, and #5 coronavirus disease. Network of the included clusters is represented in Figure 2.

Publication trend analysis

On analysing the timeline of the keywords among the top clusters we noted that the recent publication trends revolved around the research domains like oncology, chemoradiotherapy, and coronavirus disease as shown in Figure 3.

Citation Analysis

The 2792 articles published in past 5 years accumulated a total citation count of 5285 (as of June 6, 2022). Average citation per article was 1.89. Based on the articles published in the past 5 years, the H-index of the journal was 22 (as of June 6, 2022).
