New Look, More Features for ClinicalTrials.gov

ClinicalTrials.gov, the National Library of Medicine's web-based registry of approximately 47,000 clinical research studies, now has a new user interface and expanded features. The new interface provides more display options, including sponsor, size and age group. Search terms are now highlighted in results. The new "Studies by Topic" and "Study Topics" features group trials by four main categories: conditions, drug interventions, sponsors and locations. The map of study locations is also enhanced, allowing viewing of the number of registered trials in regions of the world for a specific search or for all studies in the database.
