NOT a doctor here..Zero medical background...There is an aspect of these findings that IMO need further investigation...that would identify with specificity...what exactly was the reason for the deaths...at ages on average of 54 years old.
The reduced 350 MG's didn't stop death, but in what manner did it help mitigate the timeline.
At any time,... were doses increased by virtue of continued resulting longevity?compassionate use...at what point?...it seems that 3 lived past 24 mos...that in itself is amazing...and ultimately the five alive is definitely over the top...with four disease FREE...that's absolutely astonishing given previous stats...and use of other drugs.

I guess what i'm saying is co-morbities...lifestyle...genetics have to play some part in the equation.

Remember...not a doctor!
