Someone once told me the (claimed) old protocol temporarily published on the internet would not statistically analyze the psPD group until the main group reached statistical significance. Then, I think unblinding both at the same time refers to when the trial actually crosses over and the public is made aware of the unblinded results. So I doubt very much the request was made for the psPD group alone.
The main thing is MGMT is randomized in the trial. (Bears claim LP lied or was confused about this. Huh, wonder why they'd have to rely on an outrageous accusation to keep their argument intact?)
