Internal IDs in the Clinical Data by Form folder

In the Clinical Data by Form folder, the content of the Internal IDs folder is the same for each report topic. Using the unique identifiers, you can focus a report on specific:

Subjects
Sites
Study versions
Visits
Forms

Note: If your study does not enforce unique subject numbers, site mnemonics, or visit mnemonics, you can use the SUBJECTID, SITEID, or VISITID to uniquely identify a subject, site, or visit in a report.
