- Measurements are expressed as the mean ± SD
- QST Quantitative sensory testing, PAP Postoperative axial pain, CPAP Chronic postoperative axial pain, PPT Pressure pain threshold, CPM Conditioned pain modulation, TS Temporal summation
- *Statistically significant differences between patients with and without PAP
- #Statistically significant differences between patients without PAP and patients with CPAP
- ^Eight of 21 patients with PAP developed CPAP; thus, all measurements of patients with CPAP were included in the measurements of those with PAP
