Title: Sustained serological and complete response s in HBeAg -Positive Patients treated with  
Peginterferon alfa -2b: a 6 -Year Long -Term Follow -Up of a Multicenter, Randomized, 
Controlled  Trial in China

Reviewer's report:  
 
The authors have well adressed most issues raised by the reviewers.  
 
 
I have the following comments:  
 
The numbers in the "LTFU" -Section of table 2 do not fit to the numbers given in table 3. For 
example accordi ng to table 2 there were 45 patients with HBe Negativity at LTFU in the low 
dose PEG -group (without additional antiviral treatment) and in table 3 there are 46 patients in the 
low dose PEG group without NA -therapy!  
 
For me the main conclusion of this paper is that there are no clinically relevant differences 
between the three treatment groups during the long -term follow -up.  
 
Honestly, I do not understand the clinical significance of the term "cumulative response rate" in 
the context of the paper. From table 3 it can be seen that the overall complete response rate is far 
below 70% in the high dose 48 weeks group after 6 years - and this is the most significant 
clinical end point.
