Relationship between von Willebrand factor antigen levels and liver
fibrosis stage.
The plasma levels of von Willebrand factor antigen were F0:
108.7 ± 58.9%, F1: 120.1 ± 80.8%, F2: 157.0 ± 85.0%, F3:
183.5 ± 85.0% and F4: 189.4 ± 118.2%. von Willebrand factor antigen
increased according to progression of liver fibrosis and was
directly correlated with liver fibrosis stage
(r = 0.313, p < 0.05).
F0: no fibrosis; F1: portal fibrosis widening; F2: portal fibrosis
widening with bridging fibrosis; F3: bridging fibrosis plus lobular
distortion; F4: liver cirrhosis; VWF: Ag: von Willebrand factor
antigen.
