Present pain intensity (PPI) scores in all patients

• S (+) : Time course of the PPI score in the Group S (+)
• S (-) : Time course of the PPI score in the Group S (-)

No statistically significant differences were noted in the PPI scores between the Group S (+) and the Group S (-) before or at 1 hour or 1 week after SNRB. However, the PPI scores were significantly lower at 1 hour and 1 week after SNRB than before SNRB in both the Group S (+) and the Group S (-) (*5 and *6; *7 and *8)
