That’s good data.
I don’t think Tinnitus was the core subject. They were chasing Meniere’s and Vertigo, and it reads like Tinnitus was a minor side finding. Sample size 120 and both groups did report a subjective lessening of ringing, meaning there was some placebo effect happening, despite noting the treatment group’s reported lessening was greater.
I also doubt, since tinnitus was a side study, that all 120 had tinnitus. Some or even most had Meniere’s or Vertigo. Maybe fewer with tinnitus.
Tinnitus is very subjective. Cochlear flow does not measure it. People hear ringing or they do not. For such things people are inclined to think . . . it’s imaginary. Psychosomatic.
The issue that shoots all that down is veterans suicide far more than the general population, and the suicides highly correlate to tinnitus in their records. So if there were a treatment out there that works, the VA would be on it like white on rice.
