eResource focus: metaRegister of Controlled Trials

This international database contains ongoing and some completed controlled trials in all aspects of health care.  It is free and enables users to search, register and share information about randomised control trials, as well as a separate one for mental health. Publication services are also available via the range of open access peer-reviewed journals published by our sister company, BioMed Central.
