In an effort to understand how results of human clinical trials are made public, researchers analyzed 8907 clinical trials completed in 2006-2009 and registered at ClinicalTrials.gov, the world’s largest clinical trial registry.

Only 47% of trials analyzed in their large sample provided linked publications or basic results. Despite availability of several information channels, trial record managers do not sufficiently meet the mandate to inform the public about results of clinical trials either via a linked result publication or basic results submission, although there is a temporal trend showing an increasing rate of submission of basic results.
