All studies that fall into the following definition of a clinical trial must now be registered on a publicly accessible database to be considered for publication (as required by International Committee of Medical Journal Editors, ICMJE):

Any research project that prospectively assigns human subjects to intervention and comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome.

If your research falls into this definition you must make sure you register your study before enrolment of the first patient, otherwise you may not be able to publish.  The ICMJE can provide a list of public database, examples are:

  • ClinicalTrials.gov 
  • ISRCTN Registry  

To register your trial on ClinicalTrials.gov you need to go to the login page not the main public view page.

Please contact the Research Integrity Officer if you have any comments or queries about registering.
