There is no mention of ethical approval in this study as patients with dyspeptic symptoms (early 
satiety, epigastric pain) is stro ngly associated with H pylori infection and were patients being 
treated for H pylori and subsequently tested to ensure complete eradication?  Are they invited for 
upper endoscopy and biopsy to exclude gastric neoplasia?  
How's the 'Amharic version' of trans lated and validated questionnaire being done? Any 
involvement of non -medical or language experts involvement? I' m aware that there are many 
cultures exist in Ethiopia and this needs to be explained further in the process of translation of 
questionnaires.  
 
The word ' bleaching' meant to be ? belching?  
How to explain high proportion of H pylori infection among patients with belching with AOR of 
4.7?

high propo rtion (48%)of UD in Ethiopia as compared to other countries in Asia. Any similar
