PROSPEROPROSPERO is an international database of prospectively registered systematic reviews in health and social care, welfare, public health, education, crime, justice, and international development, where there is a health related outcome. 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 duplication and reduce opportunity for reporting bias by enabling comparison of the completed review with what was planned in the protocol.
JBI Systematic Review RegisterThis register is for the use of JBI affiliated entities only. Registration of a systematic review title on the JBI website is to promote collaboration between affiliated entities via highlighting current work to other JBI review authors and to recognise that the registered topic is currently in development to avoid any unintended and/or unnecessary duplication of research effort.
Open Science FrameworkMany researchers deposit their protocols in OSF as a way of increasing research transparency.
osf.io is the preferred repository for non-clinical systematic reviews
