REDCap project setup.

1. Add instruments (eg. post scan survey )
   • setup branching logic (see REDCap Survey Logic)
2. Define events (eg. Scan, Scan_2)
   • all on arm_1. different arms have different participants (e.g. control vs clinical). See REDCap: Longitudinal vs Arm.
3. designate instruments for events (set post scan to be give on both Scan_1 and Scan_2)
4. setup survey queue. See REDCap Survey Logic.
   • logic to e.g. only show demographic form to older than 18
5. test queue and branching logic
