note:Clinical trial website useless may be but this only what we have. but do not worry anonymous don't care about it.
A report published earlier this year found that only 22% of the 738 registered trials on the website that wrapped up in 2009 and were required to report results within a year actually did so (BMJ 344, 7373–7379, 2012). The US Food and Drug Administration (FDA) maintains that the study overestimated noncompliance, based on data only the agency has access to, but criticisms continue. In May, an editorial published in the Journal of the American Medical Association deemed the registry to be “coming up short” on the requirements for data collection, as stipulated in the FDA Amendments Act of 2007 (JAMA, 307, 1861–1864, 2012).
