Abstract:

Objective ·To analyze the discipline distribution, research teams, multi-center cooperation and trend of clinical trial registration and published papers of Shanghai Jiao Tong University School of Medicine (SJTUSM) from 2012 to 2021. Methods ·On the Dimensions, and China and US clinical trial registration platforms, the clinical trial information registered by the institutions affiliated to SJTUSM from 2012 to 2021 was retrieved. Each clinical trial was classified and marked according to the classification standards such as Health Research Classification System (HRCS) and International Commission on Radiological Protection (ICRP). Clinical trial papers published by the first author or corresponding author from SJTUSM in the same period were retrieved in PubMed. EXCEL 2016 and VOSviewer 1.6.18 software were used to conduct cluster analysis and visual summary. Results ·From 2012 to 2021, Chinese researchers participated in 54 652 newly registered clinical trials worldwide, accounting for 13.63% of the global in total. Beijing, Shanghai and Guangzhou have been the top three cities with the most clinical trials in China. The number of newly registered and underdeveloped clinical trial projects in SJTUSM has been basically increased year by year in the past 10 years, but it declined slightly in 2021. In total, 3 970 clinical trials were registered by SJTUSM, in which 44.4% were registered on the Chinese clinical trial platform and 55.0% were registered on the US clinical trial platform, and 85.5% were initiated by researchers. Cancer, cardiovascular disease, oral and gastrointestinal disease, mental disease, and metabolic and endocrine disease were the major areas of clinical trial research of SJTUSM. Lung cancer research ranked the first in all 47 kinds of tumor research. The Sixth People 's Hospital, Ruijin Hospital and Renji Hospital ranked top 3 in clinical trial registration among hospitals affiliated to SJTUSM. A total of 1 898 papers (5.4%) were published in clinical trials with SJTUSM as the first author 's or correspondent author 's institution, and the research topics were mainly distributed in the fields of gastroenterology, heart disease, tumor, radiation, orthodontics and diabetes. The affiliated hospitals of Fudan University has been the main institutions of clinical trial cooperation. SJTUSM has formed core research teams in the fields of diabetes, hypertension, orthopedics, radiology and nephrology. Conclusion ·SJTUSM has obvious advantages in clinical trial research discipline and a great potential for emerging disciplines. Innovative clinical research teams have been formed in SJTUSM. Multi-center clinical trials are the norm of clinical trials, and SJTUSM has presided over international multi-center clinical trial cooperation in some fields. However, compared with the clinical trial registration in the world and other domestic regions in 2021, the number of clinical trial registrations of SJTUSM has decreased significantly, and the reasons need to be further analyzed.
