Tx ex. I believe my confusion is because hypothetically all treated patients live for 3 yrs., how would you gage a look'n in the first 2 years ?? considering that the scheduling is event driven. I understand the number of events occur that a look'n can follow but let's assume events do not occur in the time that is stated then an early look'n might not be warranted because events haven't occurred ??
