Results Disclosure
Join the Initiative

The Ottawa Statement is a consensus document that aims to guide the implementation of global trial registration. Endorsed by individuals and organisations throughout the international research community, the Statement recognises that public availability of information about all trials in healthcare is essential to ensuring ethical and scientific integrity in medical research.

The Statement outlines the fundamental principles for trial registration (Part 1), operationalisation of the protocol registration (Part 2) and of results reporting (Part 3).

Following the Ottawa Statement Part 1, which outlined the principles of trial registration, the Ottawa Group developed the principles of implementation of trial registration and is proposing them as the Ottawa Statement Part 2 and outlined the Ottawa Statement Part 3 on principles of disclosure of trial results and their implementation.

Interested parties are invited to join the Ottawa group in endorsing the Statement and to join the IMPACT initiative.
