Title: The Association of Obesity with Vascular Complications after Liver Transplantation

Reviewer: Krzysztof Zieniewicz  
 
Reviewer's report:  
 
I would like to congratulate the authors their interesting and relevant study. The importance of 
their conclusions is increasing due to growing number of obese recipients, especially in Western 
population. Cosmetic language corrections are necessary i.e. W orld Health Organization (not 
Healthy). I would hesitate whether the Nair's study, relatively old (1994 -1996, published in 
2001), should be included. It was quite different era of liver transplantation.
