Subject Visits Erroneously Described as Moved to Events

Short Name
Subject Visits Erroneously Described as Moved to Events
Affected Standard
SDTM v2.0
Description of Error

Section 1.4, Significant Changes from Prior Versions, includes the paragraph, "The Subject Visits domain, which was a special-purpose domain, has been moved to an Events class domain. The variable "SVUPDES" became a domain-specific Events class variable." This is a change that was proposed in the Internal Review version of the standard, but was not implemented in the final released standard or in the related SDTMIG v3.4.  This paragraph should be ignored; instead refer to Section 3.2.3.3 Subject Visits.
