As noted, I would say adding a dose or two of bavi to docetaxel (if that is what happened) would likely not impact survival, meaning the 5.6 month reported survival is likely a valid number.
Thanks for your opinions and discussion, bimerkjaere. It seems, though, that if the last part of your contention, above, were REALLY likely, PPHM would not have decided to combine the control arm with the lower treatment arm.
