DateVersionSummary of Changes
20202021-0801-16052.0 Draft
  • This measure was re-evaluated to fit the definition of a clinical classification measure.  The domain was changed from the QS to RS domain.
  • The EDSS v2.0 supplement was updated to the WIKI clinical classifications supplement template.
  • The RSEVAL assumption was removed from this supplement, since it is not captured on the CRF and no assumptions are made on the potential values to include in the example.
  • The example was reduced from 20 to 15 subjects. The original VISITNUM = 2 was revised to 1 and the RSLOBXFL variable was added to represent a baseline response.
  • Updated the example by adding USUBJID = "P0016" to represent how a missing visit is handled when the instrument was not filled out.
