Registration captures clinical trial details, a sanctioned set of key data elements. This set of recorded data enables the research community to share and analyze standardized clinical trial details.
The glossary on the CTRP web site at http://www.cancer.gov/aboutnci/organization/ccct/ctrp/glossary provides definitions, attributes, and examples of metadata associated with trials. You can access other CTRP resources from the same page.
As a CTRP account holder, you can search for and review a subset of registered data that has been submitted to CTRP and validated by the Clinical Trials Reporting Office (CTRO).
