Reviewer's report:  
 
Thank you for such study. No doubt that such study is important but it's a retrospective study 
which can be som ehow biased.  
Issues wi th the study include:  
- The background is missing more relevant and big studies. Please check for other references.  
 
- The method did not describe well the main points in methodology such as inclusion and 
exclusion criteria, justifica tion for the chosen period (2013 to 2015), sample size needed and 
others.  
 
- Did all women underwent hysteroscopy and why?  
 
- The statistics section is generic and irrelevant  
 
- Although the results are detailed they are confusing and most of them are diffic ult to 
understand.
