Reviewer's report:
This paper systematically analysis the level of depression and anxiety in patients
with different sub-types of Irritable Bowel Syndrome. It is an interesting and
important topic to the clinicians in the related areas. 
Following are some suggestions and questions for the authors to consider:
1. The authors should update their systematic search. 
2. I recommend authors to register their systematic reviews and meta-analysis
reports prospectively next time.
