  1. Correlation between endogenous VWF:Ag and PK parameters and bleeding frequency in severe haemophilia A subjects during three-times-weekly prophylaxis with rFVIII-FS Volume 20, Issue 1, e15–e22, Article first published online: 20 November 2013

In Lalezari S [1], e-page 19, in Table 4, the first column heading “VWF-Ag <40%” was incorrect and should read as “VWF-Ag <140%”. The percentage value should be 140% instead of 40%.
