Right, and this will surely be on the website, but just in a nutshell, for the Neutrolin we always talk about--I have it on there right now as the number of hemodialysis is around 700,000 patients on hemodialysis, and that’s 127 million catheter days. A patient would get one vial, and we’ve used the number 2.3 days, so in other words you get 0.44 vials per day, and then we’ve projected out the number of vials or cartridges. We did the same type of math in oncology. In oncology, we’re looking at Stage 3 and 4 tumor types on TPN. It’s 7,740,000 patients, and that’s 90,000 catheter days, and it’s one lock and two flushes, so that’s where I get the number three. Then on intensive care, 4 million patients, 20 million catheter days because it’s five catheter days per patient, and we used seven potential vials or cartridges per day because they’d use two locks and five flushes. One of the new things we’ve spent some market research on during this past quarter is drilling down into these spaces and talking with the physicians, and finding out they’d use a lock as well as you well know would use flushes, so we’ve incorporated locks and flushes into the calculation now. This is important in the U.S. market in particular because the product Neutrolin that has 1,000 units of heparin, that’s for hemodialysis. We’re going to bifurcate the market, though, on the oncology and the ICU markets, we’ll have a different SKU or a different product, that one will have zero heparin in it and the other will have 100 units of heparin. So that could be a cartridge market, whereas the hemodialysis would be a vial market.
