At 12 months, what percentage of the implant-only DRG stimulation group achieved the primary endpoint for pain relief?

The correct percentage of the implant-only DRG stimulation group that achieved the primary endpoint for pain relief at 12 months is 86%. This figure reflects the effectiveness of the dorsal root ganglion (DRG) stimulation method for managing pain in patients. An 86% success rate indicates that a significant majority of participants benefited from this treatment, showcasing its potential as a valuable option for chronic pain relief. Studies often highlight such results to underline the efficacy of techniques, such as DRG stimulation, in meeting therapeutic goals and improving patients' quality of life. The interpretation of these statistics is crucial for understanding the validity of this approach in pain management contexts.
