Two unexpected developments!

The apparent withdrawal from the NFK could be because (a) the organizers have decided the data to be presented were too similar to the AHA (but if so they should have spotted that earlier), (b) RVX realised they had made an error in some important statistics they were planning to present, (c) an imminent BP buyer does not want it presented for some reason. I don't think it could be anything to do with the presenter. If he is indisposed for some reason another author would stand in.

The announcement about covid-19 is confusing too. As one of us has already pointed out, it would make more sense to go directly to the clinical trial investigators. Perhaps they tried and made no progress...
