Severity bands for these items are:
- 0 = no pain
- 1-4 = no pain and mild pain
- 5-6 = moderate pain
- 7-10 = severe pain

≥ 30% represents moderate clinically important change (ePPOC uses this criteria to identify clinically significant improvement for average pain)
≥ 50% represents substantial clinically important change.
