I'm not quite up with you guys on the statistical stuff, but I don't think there's any question that A1 can yield the opioid peptide BCM-7 and A2 cannot, and that BCM7 can be potentially bad for you. One of the issues that has been subject to debate is whether and in what manner BCM-7 can get into the bloodstream and from there to other parts of the body. If it can't, then there might not be a problem with A1 milk.
On this point, Keith Woodford has just posted an article on his blogsite about important new research showing that BCM-7 can indeed cross the gut barrier into the bloodstream, and that the body's immune system tries to react to this. It also shows that in the case of autistic kids, there is a noticeable difference in how the immune system reacts, which would indicate a direct correlation between BCM-7 as measured in urine and the severity of the autism.
To quote a crucial passage from that research paper (which refers to BCM-7 as "CM-7"),
"The present study, for the first time, demonstrated that autistic children have elevated levels of CM-7 immunoreactivity in the urine (Fig. 1), and revealed the positive correlation between the content of urine CM-7 and the severity of ASD (Fig. 2)."
But Woodford says that while this finding is very important in itself, the more important point to emerge from the trial was that it is now definitely shown that BCM7 can enter the bloodstream.

I think it's important to remember that the Curtin University trial is just one of many research projects on A1/A2 being done around the world and they tend to tie in with each other. No one of them should really be analysed to death on its own.
