Glad to see that you admitted your stupid mistake. Actually you didn't admit but changed your initial response by shifting from clock-stop 1 to overall approval.
"It goes to show that a drug passing stat sig through a CHMP review is no guarantee that EMA will grant approval."
There's no guarantee but 78% of application submitted to EMA end up approved first time. Obv you could argue negatives for Anavex that would make this lower or positives for Anavex which would make this higher but that's the base % for getting through to the end and approved.
