to be in the public domain, but you should perform your own assessment. CDISC has included the RISING FROM FLOOR in the library of QRS data standards supplements. Hence, CDISC developed FTTESTCD and FTTEST for each item based on the actual text on the instrument.

3 The FT Domain Model

3.1 Assumptions for FT Domain Model

All assumptions and business rules described in the SDTMIG FT domain are applicable to this supplement. Additional assumptions specific to the RISING FROM FLOOR are listed below.

...

1. The numerical value for the time to complete the RISING FROM FLOOR is recorded using ISO 8601 format in FTORRES and FTSTRESC. Because ISO 8601 format is a text format, there are no standard numeric scores or units. The sponsor enters the time on the CRF in minutes and seconds according to their protocol. (e.g., 1 minute 10 seconds is represented in the FT domain in ISO 8601 format as "PT1M10S")

2. For the test grade (where FTTESTCD = "RISEF104"), FTORRES is populated with the text description. The numeric rating is represented in FTSTRESC and FTSTRESN.

3. If the entire instrument was not done, the first question on the CRF represents the reason the entire instrument was not done. If the reason not done is provided, then FTSTAT = "NOT DONE" and FTREASND is equal to the text written on the form for all the test codes. 

   1. If the test was not done due to disease, the record where FTTESTCD = "RISEF101" will have FTORRES and FTSTRESC equal to "No, Due to disease under study" and the test grade (FTTESTCD = "RISEF104") will be represented with a value of 1 = "Unable to walk independently"

      .

4. Some items on the RISING FROM FLOOR may be logically skipped

   Jira
   showSummary false server Issue Tracker (JIRA) serverId 85506ce4-3cb3-3d91-85ee-f633aaaf4a45 key QRSSUPP-578

   per the instrument instructions. If the test was not done because of disease, FTTESTCD = "RISEF102" and "RISEF103" are not done and are treated as logically skipped items. A record is created in ft.xpt for all items. When an item is considered a logically skipped item, it is represented as follows:

   1. FTSTAT = "NOT DONE"     

   2. FTREASND = "LOGICALLY SKIPPED ITEM"
      

   3. FTORRES, FTSTRESC, and FTSTRESN are set to null

5. Terminology:

   1. FTCAT, FTTESTCD, and FTTEST values are included in CDISC Controlled Terminology.

   2. A full list of value sets for result and units fields is provided in Section 4, SDTM Mapping Strategy.

3.2 Example for the RISING FROM FLOOR FT Domain Model

The RISING FROM FLOOR example below shows the terminology used to implement the instrument in the FT domain. This example shows the data for 1 subject collected

at the baseline visit for the RISING FROM FLOOR instrument, and data for 1 subject who did not perform the test. The example uses CDISC Controlled Terminology for FTTESTCD, FTTEST, FTORRESU, FTSTRESU,

and FTCAT. All original results, matching the CRF item response text, are represented in FTORRES. This result is then represented as a standard numeric score in FTSTRESN and as a standard character representation in FTSTRESC.

4 SDTM Mapping Strategy

This section is used for reference regarding the CRF data capture and to understand the alignment of the instrument to the SDTM FT domain. It also provides guidance on how the result and unit variables (FTORRES, FTSTRESC, FTSTRESN, FTORRESU, and FTSTRESU)
