According to the Declaration of Helsinki, registration and reporting guidelines apply to all clinical studies.

For clinical trials on Medicinal products and Medical Devices prospective reporting results within 12 months after the end of the study are also required by law.

Transparent clinical research is crucial to the accessibility and usefulness of the underlying clinical work. Clinical trials should be transparent from prior to initiation (i.e., registration) to after study completion (i.e., reporting).

We have summarized several practices for trial transparency based on regulations and ethical guidelines here:

  1. Preregistration
  2. Reporting summary results in registers
  3. Publishing summary results in a peer-reviewed journal or as a preprint
  4. Linkage of publication registry
  5. Open Access
