Bleeding phenotype according to factor level in 825 children with nonsevere hemophilia : data from the PedNet cohort
Background: Information on bleeding phenotype in nonsevere hemophilia may be used to determine target factor levels for prophylaxis or gene therapy in severe hemophilia. Objectives: To assess the association between endogenous factor level and bleeding phenotype in children with nonsevere (factor [F]VIII/FIX activity 1%-25%) hemophilia A (HA) and B without prophylaxis. Methods: Data on annualized
