"PROSPERO is an international database of prospectively registered systematic reviews in health and social care. Key features from the review protocol are recorded and maintained as a permanent record. PROSPERO aims to provide a comprehensive listing of systematic reviews registered at inception to help avoid unplanned duplication and enable comparison of reported review methods with what was planned in the protocol."
PROSPERO helps "...safeguard against selective reporting; making it possible for editors, peer reviewers and others to compare planned methods with the final report."
