is that what you're going to write in your letter of complaint?
check page 18, table 4. Here's a more detailed breakdown of the censors of the data used for approval. You've got fairly similar censoring % between the 2 arms. Slightly more on the optune arm for withdrawing and disease progression/AE but no where near enough to account for the differences on the KM curve between the two arms.
still this doesn't change the fact that they don't have reliable data to say anything about 5-year survival and in my opinion it shouldn't be legal for them to advertise that % KM figure.
