Now in the CTN Library: NIDA CTN Common Data Elements
The NIDA CTN Common Data Elements website has moved to the CTN Dissemination Library!
The CTN-CDE portal provides a single source for National Institute on Drug Abuse (NIDA) Clinical Trials Network (CTN)-recommended Common Data Elements (CDEs) of Substance Use Disorders for use in clinical trials and electronic health records (EHRs).
A “data element” describes the (data base) characteristics for a discrete piece of data that will be collected, stored or exchanged during the course of a study or a health examination, but does not include the collected data. A “common data element” is one that can be applied to multiple data sets across different studies or institutions, helping to improve data quality and promote data sharing.
