OK, based on what Jazzfunkanne said that there are 300 patients a year in Glasgow and Glasgow has a population of about 2 million, if my math is correct, that would mean that the incidence of an AN in Glasgow is 1 in about 6,600 compared to this country at 1 in 100,000. Now I realize there are a lot of variables and aberations, but going back to what I noticed before, there seems to be a lot of Scot and Scot/Irish folks on this Forum. It seems odd to me that there is such a wide disparity between Glasgow, Scotland and the United States. Of course I realize that many ANs probably go undetected in less medically sophisticated rural areas -- especially in lower income groups -- as compared to city areas -- but 6,600 compared to 100,000 is a wide range. Now if my Algebra is correct (which it may not be since I floundered around in Algebra I most of my collegiate career) using the same proportion in Glasgow, there would be 45,000 ANs in the United States every year not 3000. Why?
