Clinical Trials

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.

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 including Medline, Embase, PsycInfo, BNI and Cinahl contain references, often with informative summaries or abstracts, to journal articles including clinical trials.
