Clinical Research Metadata Repository

Find documents and data linked to clinical research studies

The Clinical Research Metadata Repository is the online tool to help scientific researchers find documents and data linked to a clinical research study, and to obtain information on the accessibility of those results. ECRIN made the Clinical Research Metadata Repository freely available for all scientific researchers. It is updated regularly through collection of data from the most important sources of information worldwide, from New Zealand to Italy and from Japan to Lebanon.


How it works

Metadata RepositoryAll scientific users can search freely and without registration via for documents and data linked to a clinical research study, and obtain information on the accessibility of those results. Where results are publicly available, a direct link to the source is provided. Where results are available under restricted access, then as far as possible the details of the access arrangements are displayed within the portal, provided with a URL to a description of the access procedure.

Metadata Repository for clinical trials data objects

The Clinical Research Metadata Repository output is non-opinionated and non-curated. This means that the data collected and aggregated is presented in a searchable form, and that there is no use of ‘expert input’ or a ‘quality filter’. The Clinical Research Metadata Repository is meant to help researchers discover clinical studies and related data objects, as there are for example protocol, information sheet and consent form, data management plan, statistical analysis plan, case report form, results, publications, descriptive metadata, etc.
