11. What are the demographics of hepatitis B genotypes in the US?

This is a study that I participated in with Dr. Chu, who’s a colleague of Anna Lok, at the University of Michigan, that tells you a little bit about the demographics of the United States. The blue is A, and the pink is D, and yellow and orange are B and C. So out here in the west, the centers that participated were Stanford and UCLA, so you can see we have large Asian populations in our practices out west. But if you go to the Northeast or the Southeast, you see more of genotype A, because there are more Caucasian and Hispanics that were entered into these studies.
