Significant differences were observed for the Physical Component Summary but not the Mental Component Summary in the basivertebral nerve ablation treatment arm at 9 and 12 months post procedure compared with baseline.
*As observed. No imputations for missing values.
†P value from a paired t-test (baseline to 9 and 12 months) for the BNV ablation arm.
