I think it was BMO that had a note that said the upsizing in the trial would increase the power. I am not a stats guru but if the effect size is smaller unless they increased the n significantly more than necessary I don't see how the power could be higher.
I didn't notice any mention of it in the press release so I don't know if its sloppy analysis or they talked to management.
I don't have the report I got thanks to a tweet by @dougheuringaria who is a great follow for information!
