See my last post. NWBO is locating ltfu, showing censors and (annoyingly) not excessively extrapolating their km curve. They are updating the raw data as they go along. DCVax is also not (yet) on the market. In short...Dr.Liau/Dr. Bosch/NWBO are responsible KM curve practitioners whilst Novocure/Dr. Stupp.... not so much.
