The participant label must be the concatenation of the Project Label, an underscore and a Participant Code.
Ex. ABC01_CMH_00000001
| Example | Definitition | Restrictions/Rules | Notes |
|---|---|---|---|
| ABC | Project Code | 3 Uppercase Letters | Chosen in coordination with KCNI admin. Preferably a project acronym. Cannot match existing project. |
| 01 | Study Code | 2 Numerals | Typically '01', unless describing divisions within a project |
| CMH | Site Code | 3 Uppercase Letters | Must be chosen from site code list HERE |
| 00000001 | Participant Code | 4-8 Alphanumeric Characters | See recommendations below |
The Participant Code denotes a specific person (or animal) within the study:
- must be 4 to 8 characters long
- preferably contains only numeric digits, but can include uppercase letters if needed
- recomended to start at 00000001 and increment as necessary
- must not contain lowercase letters, symbols, or whitespace (spaces, tabs, etc)
- must not include PHI (e.g., diagnosis), case/control status, or other sensitive information
- must not contain the characters 'PHA' in positions 4-6, since these indicate "phantom" (non-human) images in XNAT
- must not contain any coding related to location, visit, or any other code that is not representative of the subject. (eg. BAD: ABC01_CMH_V10001 - where V1 represents the first visit)
