Figures are given as median values (IQR) observed in the whole cohort and as the Spearman rank correlation coefficients (Rs) for the association between each serological marker and VWF:Ag levels, VWF:RCo and VWF RCo/Ag ratio.

*Statistically significant different level compared with healthy controls (p<0.05).

†Statistically significant correlation (p<0.01).

‡Statistically significant correlation (p<0.05).

Ag, antigen; BAFF, B-cell-activating factor; CRP, C-reactive protein; ESR, erythrocyte sedimentation rate; Hb, haemoglobin; IL, interleukin; NK cells, natural killer cells; RCo, ristocetin cofactor; Rs, Spearman rank correlation coefficients; SLE, systemic lupus erythematous; TIBC, total iron-binding capacity; TNF, tumour necrosis factor; VWF, von Willebrand Factor, WBC, white blood cell.
