Erratum

In the Letter to the Editor by Takeda et al. “Elevation of B cell-activating factor belonging to the tumour necrosis family family (BAFF) in haemophilia A patients with inhibitor” (Thromb Haemost 2009; 101: 408-410) published in the February 2009 issue of Thrombosis and Haemostasis there was an error in the title. The correct title is: “Elevation of B cell-activating factor belonging to the tumour necrosis factor family (BAFF) in haemophilia A patients with inhibitor”. The authors apologise for this oversight.
