This probably just sort of flushes it out a little more floridly. These are data from Maureen Hack, who was here two years ago talking about outcomes with premies from studying a zillion babies in Cleveland over the last 20 years. This category is sort of lumped together, because that's the Vermont-Oxford reporting that we do. But basically, if your baby weighs in this category, you have a little greater than a 50% chance of having the diagnosis. And you can see, as the birth weight goes up, the incidence goes down. So, birth weight and gestational age mirror each other very strongly.
