Reviewer's report:  
 
This is the revised manuscript describing that macrocytic anemia is associated with MELD score 
of HBV -related decompensated liver cirrhosis (LC). Authors revised several points and errors 
suggested by the reviewers. However, se veral problems are still unsolved in this manuscript.  
 
 
The clinical significance remains unclear. Which of MELD score and MCV is better predictor of 
patients' prognosis? Moreover, the relationship between MCV and other factors related to liver 
function, in cluding Child -Pugh score, remains unclear.  
 
 
 
Major points.  
 
#1. The clinical significance of this study still remains unclear. Which of MELD score and MCV 
is better predictor of patients' prognosis? Authors should show the comparison MELD score with 
MCV as a predictor of patients' prognosis. Why did the authors analyze HBV -related LC alone? 
How about HCV -related LC or NASH -related LC? Authors should discuss whether difference of 
etiology influences the association of MCV with MELD score.  
 
 
#2. The relationshi p between MCV and other factors related to liver function, including Child -
Pugh score, remains unclear. Authors should show the most significant factor associated with 
MCV in patients with LC. Is the most significant factor associated with MCV MELD score?
