title: [The registration of clinical trials has been extended to all patient-related intervention studies].
abstract: Since 2005, the International Committee of Medical Journal Editors (ICMJE) has required the registration of clinical trials. Most other medical journals embrace this policy nowadays. To date, over 40,000 trials have been registered. From July 1 2008 all research studies that prospectively assign human participants or groups of humans to one or more health-related interventions to evaluate the effects on health outcomes will be subject to registration. From each registered trial, a short abstract of the results will be posted in the registry.
