The aim of this study was to investigate the efficacy of sequential therapy for H. pylori 
eradication in patients with iDU or NUD in the Taiwanese population.  
 
 
Specific comments are as follows,  
 
1. P3, Abstract: Please clearly show wh ether this study was a prospective or retrospective 
study in the Method section.  
 
2. P4, Abstract: How about the overall comparison results of sequential therapy and 
standard triple therapy (including all patients)? Please show the data in the abstract.  
 
3. P6, lines 11: standard triple therapy use of proton pump inhibitors => standard triple 
therapy using proton pump inhibitor  
 
4. Results: Please perform multivariate analysis to investigate the independent factors 
predicting eradication failure in this study. Was type of disease an independent factor 
determining eradication outcome in this study?  
 
5. Results: How about the antibio tic resistance profile of H pylori strains in this study?  
 
6. Results: Please show the overall comparison results of sequential therapy and standard 
triple therapy in the Result section.  
 
7. Discussion: Please discuss the reason why patients with iDU had a h igher eradication rate 
of sequential therapy than those with non -ulcer dyspepsia.
