| 2.0 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, because 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 16 subjects. The original VISITNUM = 2 was revised to 1 and the RSLOBXFL variable was added to represent a baseline response.
- The example was updated by adding USUBJID = "P0016" to represent how a missing visit is handled when the instrument was not filled out.
- Added the description of the relationship

The Kurtzke Expanded Disability Status Scale (EDSS) and Kurtzke Functional Systems Scores (KFSS) instruments are intended to be used in conjunction with one another. The KFSS should first be administered by the evaluator; results from this assessment are then applied to determine an EDSS scale score (Kurtzke, 1983). A change in the EDSS should only occur if there has been a change of 1 or more

."). For the EDSS, RSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables RSSTRESC and RSSTRESN.
Three responses to the EDSS ratings exceeded the 200-character limit for the RSORRES variable and needed to be reduced to fewer than 200 characters. Section 4, SDTM Mapping Strategy, indicates which item responses were revised in order to fit the 200-character limit.
Terminology
RSCAT, RSTESTCD, and RSTEST values are included in CDISC Controlled Terminology.
A full list of value sets for the result fields is provided in Section 4, SDTM Mapping Strategy.
