What is it? Why is it important?

Study Registries are web-based platforms where detailed information on ongoing and completed studies are published.

Researchers have an ethical obligation to make their study results public, whether they are positive, negative or inconclusive.Researchers have an ethical obligation to make their study results public, whether they are positive, negative or inconclusive. Unpublished research is unethical because study participants become exposed to potential risks as a result study participation, and it includes a waste of invested resources and scientific experience.


As a minimum, study results should be published in a registry recognized by the World Health Organization (WHO), such as the ClinicalTrials.gov registry,


A study registry has many advantages as it:

  • Functions as a public record where study results are presented in a standardized format
  • Complies with required ethical obligations towards study participants
  • Ensures that research results contribute to overall medical knowledge
  • Reduced publication and outcome reporting biases
  • Facilitates systematic reviews and other research literature reviews

What do I need to do?

As a SP-INV:

  • Update all registries that were previously selected during study set-up, irrespective whether the study was completed as planned, discontinued, or interrupted
  • Ensure that for all publications, measures are taken to maintain the confidentiality of study participants



  • Registries have clear requirements regarding type of information that must be published (e.g. recruited participants, study design and methods, results, the discussion and interpretation of results)
  • Sharing scientific information is an important mean to further clinical research with the goal to provide improved treatment options to the general population
  • Trial results should therefore be shared with the scientific community, medical professionals, and the public through conferences, presentations, press releases, or other means of dissemination
