ABSTRACT=<p><bold>Purpose:</bold> The coronavirus disease 2019 (COVID-19) outbreak, which began in December 2019, has not been completely controlled; therefore, COVID-19 has received much attention from countries around the world. Many related clinical studies, such as clinical trials, have been published, but to the knowledge of the authors, there has been no bibliometric analysis of these publications focusing on clinical research studies on COVID-19.</p><p><bold>Methods:</bold> Global publications on COVID-19 from January 2020 to December 2020 were extracted from the Web of Science (WOS) collection database. The VOSviewer software and CiteSpace were employed to perform a bibliometric study. In addition, we obtained information on relevant clinical trials from the website <ext-link ext-link-type="uri" xlink:href="http://clinicaltrials.gov" xmlns:xlink="http://www.w3.org/1999/xlink">http://clinicaltrials.gov</ext-link>.</p><p><bold>Results:</bold> China published most of the articles in this field and had the highest number of citations and H-index. The <italic>Journal of Medical Virology</italic> published most of the articles related to COVID-19. In terms of institutions, Huazhong University of Science and Technology had the most publications, and Wang, JW received the highest number of citations.</p><p><bold>Conclusion:</bold> The diagnosis, prevention, and prognosis of COVID-19 are still the focus of attention at present. The overall analysis of the disease were identified as the emerging topics from the perspectives of epidemiology and statistics. However, finding an effective treatment remains the focus of clinical trials.</p>
