Reviewer's report:  
Dear author : 
 I think your study as an interesting one. It demonstrated the relationship between cirrhosis and 
the survival of cHCC -CC. Still, there were some concerns showed be explained:  
1. By path ological results, we could not only define cirrhosis as positive and negative, but also 
assess the severity. So could the severity provide more information? I suggest you try to 
group the patients by severity;  
2. Patient characteristics and outcomes should  be displayed in two separate part to make the 
results more systematic.  
3. In the outcomes, the median time to recurrence and median overall survival should be also 
compared.  
4. The relationship between cirrhosis and other clinical factors should be studied.
