...and herein lies the central issue with that. With our tiny survey number, one tenth of Neuromod's, we had at least two cases of very serious worsening, which is significant. I don't believe this was reflected in Neuromod's large trial data so the only conclusion I can reach is, it's either a statistical anomaly or something else is at play. I fear we'll never really know.
I think it's clear, actually, but let me all know if I am understanding this correctly.
Lenire had a very large dropout of people (20%?), who were labelled as non-compliant because they stopped before the end of the planned treatment.
That means they have been excluded from the final statistics.
But why have they dropped earlier? The main reason I can think of is worsening, and of such level as to force one to stop the treatment. I don't think anyone in the trial would have stopped the treatment lightly given it is the only hope to improve tinnitus at the moment.
So if someone has a temporary but tolerable worsening, one continues the treatment to the end, and perhaps by the end the worsening has resolved. However, if one has a terrible worsening, one stops, and does not make it to the end.
When Neuromod claims there have been no permanent worsening, are they including the people who were dropping out?
If not, and I believe they aren't, then that is where the permanent worsening would be hidden.
So it would be all consistent if this is what happened, and we would have that permanent worsening are within the 20% who dropped out.
If instead Neuromod checked on the dropped out patients to see that their worsening cleared up then indeed we have a mystery. Hopefully the paper, coming out in about 10 days apparently, clarifies that.
