Can you elaborate ... what do you mean? LTFU ... some patients were "lost to follow up"? And your assumption is that perhaps approx 12 or more patients were lost to follow up and as of early 2017 interim blinded data were included in the control group who had not yet progressed, and as of the recent 2018 data presented by LL at SNO these 12 or more patients had suddenly been "found" and determined to have progressed, and determined to have received DCVax-L at some point during the trial?? (BTW: hard to fathom that there are now 200,000 posts on this NWBO ihub board).
