Abstract

Background: East Asia is the most dynamic region in the world and includes three major countries: Japan, South Korea and China. Due to rapid economic growth, orthopedics research in East Asia has achieved great advances during the past 10 years. However, the current status of orthopedic research in Japan, South Korea and China is still unclear.

Aim: To understand the current status of orthopedic research in Japan, South Korea, and China.

Methods: Journals listed in the ''Orthopedics'' category of Science Citation Index Expanded subject categories were included. The PubMed and Web of Knowledge electronic databases were searched to identify scientific publications from the selected journals written by researchers from Japan, South Korea and China. A systematic analysis was conducted to analyze orthopedic research articles published in the three countries based on the number of articles, study design, impact factors (IFs) and citations. Furthermore, we also ranked the top 10 countries worldwide with the highest publications in the past 10 years. Additionally, we ranked the top 10 countries with the highest number of publications in the world in the past 10 years. Statistical analyses were performed using SPSS 20.0 software (SPSS Inc., Chicago, IL, United States), and statistical results are given in Tables and Figures. The Kruskal-Wallis test and the Mann-Whitney test were used to detect differences between countries. The tendency regarding the number of articles was analyzed by curvilinear regression. A two-tailed P < 0.05 was considered significant.

Results: From 2012-2021, a total of 144518 articles were published in the 86 selected orthopedic journals. During this period, the number of worldwide published orthopedic articles has shown an annual increasing trend. A total of 27164 orthopedic research articles were published by Japan, South Korea and China during the past 10 years; 44.32% were from China, 32.98% were from Japan, and 22.70% were from South Korea. From 2012 to 2021, the annual number of articles markedly increased in each of the three countries. Over time, the worldwide share of articles increased substantially in South Korea (3.37% to 6.53%, P < 0.001) and China (5.29% to 9.61%, P < 0.001). However, the worldwide share of articles significantly decreased in Japan (5.22% to 3.80%, P < 0.001). The annual total IFs of articles from China were well above those of articles from Japan and South Korea (36597.69 vs 27244.48 vs 20657.83, P < 0.05). There was no significant difference among the articles in the top 10 high-IF orthopedics journals published from those three countries [South Korea (800) > China (787) > Japan (646), P > 0.05].

Conclusion: Over the past 10 years, China's scientific publications in orthopedic journals have shown an increasing trend. Considering the relative scale of the populations, Japan and South Korea have outpaced China with respect to quality.

东亚三国骨科科学出版物(2012-2021)。
背景:东亚是世界上最具活力的地区,包括三个主要国家:日本、韩国和中国。由于经济的快速增长,东亚地区的骨科研究在过去的10年里取得了很大的进步。然而,日本、韩国和中国的骨科研究现状尚不明朗。目的:了解日本、韩国、中国骨科研究现状。方法:纳入科学引文索引扩展学科分类中“骨科”类收录的期刊。检索了PubMed和Web of Knowledge电子数据库,以从日本、韩国和中国的研究人员撰写的选定期刊中确定科学出版物。根据文章数量、研究设计、影响因子(IFs)和引用次数对三国骨科研究论文进行系统分析。此外,我们还对过去10年全球发表论文最多的10个国家进行了排名。此外,我们还对过去10年全球发表论文数量最多的10个国家进行了排名。采用SPSS 20.0软件(SPSS Inc., Chicago, IL, United States)进行统计分析,统计结果以表格和图表给出。Kruskal-Wallis测试和Mann-Whitney测试被用来检测国家之间的差异。用曲线回归分析了文章数量的变化趋势。双尾P < 0.05为显著性。结果:2012-2021年,入选86种骨科期刊共发表论文144518篇。在此期间,世界范围内发表的骨科文章数量呈逐年增加的趋势。近10年,日本、韩国和中国共发表骨科研究论文27164篇;中国占44.32%,日本占32.98%,韩国占22.70%。从2012年到2021年,这三个国家每年的文章数量都显著增加。随着时间的推移,文章的全球份额在韩国(3.37%至6.53%,P < 0.001)和中国(5.29%至9.61%,P < 0.001)大幅增加。然而,日本在世界范围内的文章份额显著下降(5.22%至3.80%,P < 0.001)。中国的年度总IFs远高于日本和韩国(36597.69 vs 27244.48 vs 20657.83, P < 0.05)。三国骨科高影响因子前10位期刊发表的文章数差异无统计学意义[韩国(800篇)>中国(787篇)>日本(646篇),P > 0.05]。结论:近10年来,中国在骨科期刊上发表的科学论文呈上升趋势。考虑到人口的相对规模,日本和韩国在质量方面已经超过了中国。
