| Abstract |
Background
Current research on nontuberculous mycobacteria (NTM) is multidisciplinary; thus, proper organization is necessary to obtain comprehensive insights. Therefore, a bibliometric analysis was performed to identify NTM research characteristics in South Korea.
Methods
The Web of Science was searched for NTM articles authored by Koreans at Korean institutions until March 2023. We collected data on authors, publication year, article type, study design, research area, citations, research institutes, and funding sources for analysis.
Results
Of the 28,092 articles on NTM, Koreans authored 868. After excluding 167 unrelated studies, 701 relevant articles were analyzed. The first study was from 1992, with publication rates markedly increasing from 2004 onwards. Basic research constituted 41.3% (n=290) of papers, whereas clinical research represented 44.7% (n=313). Basic research consisted mostly of biochemistry studies (n=74, 10.6%), while clinical research primarily involved retrospective studies (n=113, 16.1%). Median citations were highest for systematic reviews and meta-analyses (median 23, interquartile range 15–93). Fifty-four institutions participated in NTM research, with the top five contributing to 71% (n=498) of the publications. The National Research Foundation of Korea was the most significant funding source, supporting 181 studies (32.5% of funded articles).
Conclusion
The quality and quantity of NTM research in South Korea has improved. However, it was concentrated within a few institutions and largely funded by few sources. Future research should use more diverse funding sources, be conducted in more institutions, and prioritize prospective study designs to enhance the understanding and treatment of NTM. |
