Reviewer's report:  
 
This study analyzes the potential association between GASTRIC H. pylori and COLON 
adenoma polyps occurrence in a Chinese cohort. The study design is sound as far as to 
establishing the association between these two variables. However, the pathway analysis is NOT 
correct since we are talking about GASTRIC NOT COLON -located H. pylori. As such I think 
the conclusions drawn from the pathway analysis are NOT correct. This has also an effect on the 
Discussion section that is weak and need major redrafting to highlight the s imple association 
with potential valid explanations rather than the presented pathway analysis.  
The paper also needs major language editing.
