Sorry if I confused you and PGS. I wasn't aware that there was any other way to calculate the endpoint without comparing the difference in the two arms. But that aside, I would seriously like to know how you can simultaneously conclude that the PFS (just to be clear I mean the difference) is going to be "weeks" AND that the trial is likely (60%) to meet the 33% PFS endpoint. That would mean the placebo arm would have to be about what, 18 or 19 weeks? Sorry but given the final endpoint wasn't reached until Nov. I just don't see how you can reach that conclusion.
