Well first off, the language is ambiguous.
"In total, 58 patients with tinnitus who did not respond to medications were enrolled in the TRT program.
Medications for what? Tinnitus? Depression? Anxiety? What?
"After six months of TRT, most of the patients found remarkable improvement in the symptoms,"
Which symptoms? Tinnitus? Hyperacusis? Depression? Anxiety?
Obviously the medications are anti-depressants and anti-anxiety drugs, and the symptoms are depression and anxiety.
One day we will look back at stuff like this as if it's equivalent to blood-letting and drinking camel urine.
I can see some half assed know it all ENT reading over that and being like, "Medications, hum ho hum ho. Symptoms, ah yes the symptoms. I will recommend this to all my patients complaining from tinnitus." and coming away from it actually thinking that it will make their tinnitus less loud.
