Reviewer's report : 
 
The paper by Lee et al. aimed to investigate the cumulative incidence of HCC and evaluate 
HBsAg seroclearence in patients undergoing NA -induced HBeAg seroclearence. It is an 
interesting paper facing a problem epidemiologically very important in south east Asia. The 
statistical analysis is correct and with the limitations that have already been underlined by the 
authors themselves, can be of interest for BMC gastroenterology readers.  
 
 
There are only minor points that have to be addressed:  
 
1. It would be interesting to be tter define if young subjects treated with NA had already 
experienced an ifn based treatment without response or if they had contraindications  
 
2. In Table 1 please correct the sum M+F (which should be 203)  
 
3. In Figures 1b, 1c and 2b the authors report a difference between the curves and should 
specify in the materials and methods section the test they used, put it also in the results 
and in the figures beside the P value.
