Fig. 1. Association between genotypes at c.2771, VWF:Ag and FVIII:C levels in healthy controls according to ABO blood group.
*, ** and ***indicate significant (p<0.05, p<0.01 and p<0.0001, Mann-Whitney test) differences between median values of (A) VWF:Ag and (B) FVIII:C amongst HC, depending on their c.2771 genotype. “All” refers to the entire HC population, “O” = blood group O and “Non-O” = blood groups other than O.
