Table 2 Tinnitus severity survey reporting during study duration, n = 22

Survey	Baseline^a	Post-stimulation Session Nadir^a	Difference^a,b	95% CI for difference
THI	48 (15)	17 (17)	− 31 (14)	− 38 to − 25
TFI	60 (13)	25 (20)	− 35 (16)	− 42 to − 28

THI Tinnitus Handicap Inventory; TFI Tinnitus Functional Index; VAS Visual Analog Scale
^aSummarized with mean (SD)
^bDefined as lowest post-stimulation score minus baseline score. Baseline scores were defined as the mean of the enrollment, baseline evaluation 1, baseline evaluation 2, baseline evaluation 3, and pre-stimulation 1 scores. Post-stimulation session nadir scores were defined as the lowest score reported following a stimulation session
