13 eligible RTs with a total of 1345 patients were included in this meta-analysis. The meta-analysis results showed that the 1-month response rate, 3-month response rate, 6-month response rate, and overall response rate of TRT with drugs for tinnitus were higher than that of drugs only (P < 0.05). The results demonstrated that the THI (Tinnitus Handicap Inventory) scale after the treatment period of TRT with medications for tinnitus was lower than that of drugs only (P < 0.05).
