The authors need to carefully revise their manuscript to be a more concise,
readable, and logical writing. Because the formation of portal vein thrombosis is
related to many factors in patients with hepatocellular carcinoma, it is hard to
believe there is a firmed correlation between portal vein thrombosis and blood
folate level if the authors did not do a multivariate analysis.
