Reviewer's report:
This is a well-designed case-control study, and does add something new to the field. However,
there are some closure issues that should be addressed.

3. Please add the flowchart of the study to the manuscript.
4. In methods, line 109-110, why did you exclude the patients from the study? Is there any
exclusion criteria in your study protocols? Explain them.
