What this research found
TRT was not superior to standard of care — all three arms improved substantially (within-group TQ effect sizes −1.32, −1.16, −1.01) with few between-group differences. 77.5% (86/111 with data) achieved ≥7-point TQ reduction at 18 months.
Follow-up analyses attribute most benefit to the counseling component, not the sound generators.
Limitations and conflicts of interest
Military population with adequate hearing.
Funding / conflicts: NIH-funded.
