I agree with your sentiment. The fact that the presentation has now been removed indicates the issues raised are valid. This needs to be clarified before market opening or keep the stock halted until it is.
However, I cannot phantom that the statistical analysis and p-value hinges on these slides. If it does, that we be the fuck up of the century.
It is all fine. This was a late-breaking abstract at a scientific conference - despite Brodkin and Heilbut trying to turn it into an equity-bashing show. Everything will be great. They will clean it all up, re-release, put a PR and a CC together with Q&A and then lift the halt. Might not trade again until Monday but that is OK.
