ISRCTN registry
The ISRCTN registry is a primary clinical trial registry recognised by WHO and ICMJE that accepts all clinical research studies (whether proposed, ongoing or completed), providing content validation and curation and the unique identification number necessary for publication. All study records in the database are freely accessible and searchable.
International Clinical Trials Registry Platform (ICTRP)
The ICTRP Search Portal aims to provide a single point of access to information about ongoing and completed clinical trials. It provides a searchable database containing the trial registration data sets made available by data providers around the world meeting criteria for content and quality control.
Healthcare Databases*
Healthcare databases including Medline, Embase and Cinahl contain references, often with informative summaries or abstracts, to journal articles including clinical trials.
