Reviewer's report:  
Dear Editor,  
I have revised the paper "An App raisal of Clinical Guidelines for Constipation: a Right Attitude 
Towards to Guidelines" and I have some suggestions regarding the paper as listed below.  
 
Yours sincerely,  
 
Abstract  
1. The sentence needs to be corrected so as to not start with "And" "And on ly 5 (23.81) 
guidelines reported methodological expertise were in guideline developing teams."  
 
Introduction  
1. Please remove 1 full stop at the end of the 3rd paragraph that is excess.  
2. Please give the exact full names before the abbreviations such as "CPGs" at the first place you 
state.  
 
Materials and Methods  
 
Data Searching  
1. It is stated in the text that the authors searched the database with no restriction on language 
in this sect ion. However in the "Selections of Guidelines section" the authors state on the 
3rd item that the language was restricted to English and Chinese only in the inclusion 
criteria. The authors already state this a limitation of paper that they did not cover 
guidelines in other languages.The authors will either need to state in "Selections of 
Guidelines section" that they restrict language to English and Chinese or perhaps they 
should only focus on English language and remove study in Chinese to be fair. This st ill 
needs to be mentioned as a limitation.  
2. Please give full names before abbreviations throughout text at the first place they are 
given.  
3. "Clarity of presentation" should be "Clarity and presentation."
