Note. Hemophilia severity is defined based on the level of factor activity circulating in the blood. In this table, “mild” is defined as greater than 5% baseline clotting factor activity; “moderate” is defined as 1–5% baseline clotting factor activity; “severe” is defined as less than 1% baseline clotting factor activity; and “severity unknown” is reported if the baseline factor activity is missing or unknown. Males and females with factor VIII and IX deficiency are classified the same. Beginning with the September 2020 Report, data for persons with baseline factor activity >=40% are displayed separately from persons with greater than 5% and less than 40% activity.
† The HTC Population Profile contains 37 transsexual individuals. For confidentiality purposes, the number of transsexual patients is too small to report by year or other characteristics. Transsexual patients have been included in the counts of male and female according to the sex assigned to them at birth since hemophilia and von Willebrand disease, the most common congenital bleeding disorders, affect the sexes differently.
* Counts of five or fewer have been suppressed to protect patient confidentiality. Additional cells may be suppressed to prevent derivation of these counts by subtraction.
