Statistical analysis: Cox proportional hazard models with backwards elimination were performed to assess risk factors for the incidence of portal vein thrombosis during follow-up. p values < 0.05 are indicated in bold

ADAMTS13 a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13, HVPG hepatic venous pressure gradient, MELD model of end stage liver disease, VWF-Ag von Willebrand factor antigen, VWF-N released N-terminal propeptide of VWF, VWF-A neoepitope of ADAMTS13-mediated degradation of VWF, CRP C-reactive protein
