Figure 2. Baseline quantitative sensory testing results in healthy controls and patients.

Figure 2

Patients were divided by dose to those with average daily dosing above and below 100mg oral morphine equivalents (OME). There were no differences between healthy controls and either patient group; however, the patients in the >100 mg OME were significantly more sensitive for tolerance and showed similar trends for threshold and Pain50. When observing all 3 groups, a pattern was observed to show patients <100 mg OME being more pain tolerant and those >100 mg OME being more pain sensitive when compared to the healthy controls.
