No = patient number for reference to figures; Dur = tinnitus duration (years, months); M Freq = centre frequency of masker (active) stimulus (kHz); B = bilateral; BW = bandwidth; C = control; Freq = centre frequency of stimulus; Lat = laterality; M = masker; THI = tinnitus handicap inventory score (/100); Length = duration of masker and control stimuli (s); Mod = type of tinnitus modification achieved (RI = residual inhibition; RE = residual excitation); M dur = mean duration (s) in which tinnitus rating is non-zero (i.e. modified) following each masker stimulus (including following maskers where no tinnitus modification occurred); Con. Ind. = consistency index, a measure of how much of the total tinnitus modification was due to the masker (not control) stimulus (1 = all modifications due to masker stimulus, 0 = tinnitus modified equally by masker and control stimuli), negative values, indicating greater efficacy of control than masker stimulus, are possible but did not occur; STD = standard deviation of duration of tinnitus modification by the masker stimulus (normalized to mean duration of modification, i.e. mean = 1); Data = total data length per condition used for final analysis (s); PTA = abnormal frequencies on pure tone audiometry (threshold, frequency, ear); TEOAEs = frequency bands exhibiting reduced transient evoked otoacoustic emissions (frequencies, ear); ‘x’ indicates where transient evoked otoacoustic emission data were not available. sMRI inhibition = whether subject’s own (Y) or template (N) structural image was used for analysis. SNHL = sensorineural hearing loss; NSAIDS = non-steroidal anti-inflammatory drugs.
