Primary outcome score, total THI mean (SD), from study entry through 18‐month assessment for participants treated with TRT or SC. SC intention‐to‐treat analysis uses data set with last‐data‐carried forward for missing data from participant drop‐out. SC per‐protocol analysis uses data only from participants completing the study with no missing assessments. Within group comparison to entry values: *p < .05, ^†p < .005, ^‡p < .000. Shaded box denotes p < .05 between group comparison of TRT and SC. TRT = tinnitus retraining therapy; SC = standard of care; SD = standard deviation.
