Objective The aim of this review is to characterize current status of global TCM clinical trials registered in ClinicalTrials.gov. Methods We examined all the trials registered within ClinicalTrials.gov up to 25 September 2015, focusing on study interventions to identify TCM-related trials, and extracted 1,270 TCM trials from the data set. Results Overall, 691 (54.4%) trials were acupuncture, and 454 (35.8%) trials were herbal medicines. Differences in TCM trial intervention types were also evident among the specific therapeutic areas. Among all trials, 55.7% that were small studies enrolled <100 subjects, and only 8.7% of completed studies had reported results of trials. As for the location, the United States was second to China in conducting the most TCM trials. ConclusionThis review is the first snapshot of the landscape of TCM clinical trials registered in ClinicalTrials.gov, providing the basis for treatment and prevention of diseases within TCM and offering useful information that will guide future research on TCM.
Evolution and enrichment of CDISC terminologies are driven by the active interception of the research community’s semantic needs and by a robust development and publication process, managed jointly by NCI-EVS and CDISC. CDISC terminology integration within the rich semantic infrastructure of the NCIt provides additional benefits in knowledge representation as well as mapping to other reference sources and data standards, enabling semantic interoperability and data integration across multiple data standards and models. The technology, services, and processes that NCI-EVS employs to support CDISC have yielded a terminology set that is robust, fit for purpose, and concisely defined, allowing for efficient regulatory review of medical products. These same technologies, services, and processes will aid the current effort to expand the utility of CDISC standards for Real-World Data (RWD) analysis to better support the generation of Real-World Evidence (RWE).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
