Reviewer's report:  
I compliment the authors for their work. However ,there are a few points to ponder  
1. The background/ introduction is too l ong. This needs to be reduced  
2. The dietary practices in the study area need to be mentioned as it is a major risk factor for 
GERD  
3. Comparison of your data with studies from South east Asia  and places having similar dietary 
practices eg. southern India  would be very useful in such a study  
4. The results include lot of repetition of what is shown in tables and figures. This needs to be 
modified.
