Table 3 Changes in headache disability (HIT-6) and quality of life (SF-36v2 physical component score (PCS) and mental component score (MCS)) from baseline to 12 months post-microstimulator insertion are provided (mean ± SD (range))

From: Sphenopalatine ganglion stimulation for cluster headache, results from a large, open-label European registry
