What are the ICMJE requirements for clinical trials registration?
The ICMJE member journals will require, as a condition of consideration for publication in their journals, registration in a public trials registry.

The ICMJE defines a clinical trial as any research project that prospectively assigns human subjects to intervention or concurrent comparison or control groups to study the cause-and-effect relationship between a medical intervention and a health outcome. Medical interventions include drugs, surgical procedures, devices, behavioral treatments, process-of-care changes, and the like.
