RESULTS:
TG, NRS, NTG, pain
Thirty patients allocated to the “Trial Group” (TG) and 36 patients allocated to the “No Trial Group” (NTG) completed outcome assessment at 36-month follow-up. Although there was a reduction in NRS pain and improvements in utility scores from baseline to 36 months in both groups, there was no difference in the primary outcome of pain intensity NRS between TG and NTG (adjusted mean difference: −0.60, 95% CI: −1.83 to 0.63), EuroQol-5 Dimension utility values (adjusted mean difference: −0.02, 95% CI: −0.13 to 0.10), or proportion of pain responders (33% TG vs 31% NTG). No differences were observed between the groups for the likelihood of spinal cord stimulation device explant or reporting an adverse advent up to 36-month follow-up.
