*Only time points with ≥3 observations are plotted. Steady-state mean trough is calculated from all observations at any time point. The mean dose for patients receiving prophylaxis every 7 days was 37 IU/kg.
*The median AsBR for patients who started and stayed on 7- or 14-day prophylaxis was 0. For patients who switched to prophylaxis from on-demand, the median AsBR was 0.7.
