Editorial[A review of international clinical trial registration].
Clinical trials play a critical role in medical research. However, only a few clinical trials conducted at present have been registered at various clinical trial registries. Clinical trial registration can prevent bias in these registered trials effectively and avoid unnecessary waste of resources due to meaningless repeats. ⋯ Great attention has been paid to the importance and necessity of clinical trial registration. This review briefly introduced the definition, justification, contents, history, current status of clinical trial registration, and introduced the information regarding important international clinical trial registries in detail. Clinical trial registration should be developed toward a transparent, compulsory and comprehensive stage.
