  1. Pain intensity in centimeter (0–10). Reference category (exposure absent). Depression (0 = absent/ 1 = present), Alexithymia (0 = absent/ 1 = present), Work Status (0 = Not worker, 1 = Worker)*
  2. A non-significant (p > 0.05) Brant test indicates that the proportional odds assumption is not violated
