>The most interesting part is that the Statistical Review makes it very clear that the exact form of the Cox Regression model was NOT prespecified.<
Not only was it not prespecified (despite what mitch said), DNDN never gave the impression that the Cox analysis was done on something other than an ITT population. We now know that ~10% of the patients were thrown out, in a manner that was favorable to the provenge arm.
Deception in biotechs is, sadly, the rule rather than the exception.
