What do you think of the Kaplan-Meier curves for PFS in Figure 6? Looks like a significant population is showing prolonged PFS. "Significant" ? that was either 1 or 2 patients ( I am on a netbook and counting this chart is hard). The curves look very close. BTW, Is there a standard presentation of a K/M chart if the last patient is censored ? EDIT: Forget the above dumb question. Obviously it was the last patient who was censored, and he was the only one on the tail.
