Title: 
Analysis of related factors of portal vein thrombosis in liver cirrhosis

Reviewer's report:
The study "Analysis of related factors of portal vein thrombosis in liver
cirrhosis" aimed to investigate the role of IL-6TNF-
α
Protein C and
Thromboelastography as a predictor of portal vein thrombosis (PVT) 
in patients
with liver cirrhosis. The autors concluded that 
TNF-
α
, K, APTT, the diameter of
the portal vein and the history of splenectomy or embolism were the related
factors of PVT formation, but IL-6 was not related to the formation of PVT.
The study is focused on an interesting topic and well-written.
I think it could be useful for the readers of the journal.
