RELREF Dataset
The Related References Dataset was created for nonclinical in vitro genetic toxicology assays. This dataset shows each source of information (REFID), how it is related to the study design (STUDYID, SETCD), and how it relates to other sources of information on the assay (PARENT, LEVEL, LVLDESC).
SDTM v2.1 Metadata Check for Class and Dataset Specification Table Beta 1
Metadata check macro is applied. Make sure all Confluence WIKI macros e.g., JIRA, Status, are removed prior to publication. This notice is provided as a visual reminder. It will be removed during final publication. Release Notes
