To the best of our knowledge, the following journals have policies regarding the registration of clinical trials. These deadlines will be of use for registration of clinical trials in progress. (Deadlines may change, and those planning to submit papers are encouraged to confirm this information with each journal.)
BMJ and Journals Affiliated with the ICMJE:
Trials already in progress must be registered by September 13, 2005.
Anteriosclerosis, Thrombosis, and Vascular Biology; Circulation; Circulation Research; Hypertension; Stroke:
These journals support ICMJE guidelines.
Archives of Dermatology:
This journal supports ICMJE guidelines.
Journal of the American Society of Nephrology; Nephrology, Dialysis, Transplantation; The American Journal of Transplantation; The American Journal of Kidney Diseases; Kidney International; Transplantation:
Trials undertaken from before January 2006 must be registered by April 1, 2006.
UMIN-CTR encourages the registration of trials to meet the above conditions.
Meanwhile, in order to accommodate the publication of information for the greatest number of clinical trials, UMIN-CTR will accept registrations for trials after this deadline.
However, UMIN-CTR cannot take any responsibility for the outcomes of trials (for example, if a paper based on registered trial research is not accepted due to the timing of trial registration) registered after the onset of patient enrollment. Responsibility for the trials rests solely with the organizations or individual researchers conducting the trials.
