 Yes, we've done some fair amount of research on price transparency, and we found that price transparency is, number one, not adhered to. Our evaluation of NCI-designated cancer centers found that less than a quarter were adherent. But of the prices that were posted, they were a huge variation. So for a single service, one hospital was charging $300. Another one was charging $30,000 for the same service. These are all at NCI-designated cancer centers.
