Reporting "basic results" in ClinicalTrials.gov.

Growing awareness of selective publication of research studies (“publication bias”) and the selective reporting of outcomes in publications (“outcome reporting bias”),1 has led policymakers to call for increased “clinical trial transparency” through the public disclosure of key information about clinical trials.2 A US federal law3 enacted in 2007 mandates registration and results reporting for certain clinical trials of drugs, biological products, and devices, regardless of study funding source, at ClinicalTrials.gov, an online registry and results database operated by the National Library of Medicine of the National Institutes of Health (NIH). 
 
Table 1 summarizes the goals of the results database. The theoretical benefits and limitations of non-peer-reviewed public results databases have been discussed elsewhere.4–6 This article summarizes the current requirements for reporting results and describes how to submit results data elements to the ClinicalTrials.gov results database. These tips for creating clear, understandable entries may be kept as a resource for use when preparing to enter results data for a clinical trial. A previous “Medical Writing Tips” article focused on trial registration.7
