  1. n = 21 includes only subjects who completed all test sessions and had a complete data set available.
  2. Normally distributed data is shown as mean ± SD, otherwise as median (IQR).
  3. LS learning session, OS opioid session, VAS visual analog pain scale rating from 0 to 100, 0 meaning no pain and 100 the worst imaginable pain.
