They are prevented from sharing the data, not just with the public, but with three of the authors of the paper! That's pretty tight security. I wonder if any of the other authors have seen it.

One of the authors of the paper is the founder/CEO of Surgisphere so presumably he has permission to see the "data" (assuming it exists) and has convinced his co-authors to take his word for it.
