The ClinicalTrials.gov results database now offers summary trial data that were not previously available publicly. A new article, published in The New England Journal of Medicine, summarizes the updates, key issues, and limitations of the database. However, according to the authors, ClinicalTrials.gov is continually adding features and linkages to facilitate the use and repackaging of the data by different audiences. The article provides some good food for thought as we’re looking for additional public data sources to expand our research networking tool UCSF Profiles.
