^*Oklahoma City VA Hospital is staffed by OUMC hematologists

^**Total individual patients after excluding duplicate patients reported by more than one site. Some patients were included in both the children and adults estimates because they were seen both before and after their sixteenth birthday; these patients were only counted once in the overall prevalence estimates. Therefore the total number is 1,147 rather than 1,159.
