Reviewer's report:
This paper aims to evaluate the variations in biomarkers of dyslipidemia and
dysbiosis during the menstrual cycle
I have concerns regarding the study design. Please:
1) abstract should be reworded and report objective, number of included
participants, and details on study design are needed
2) I would try to increase the sample size
3) Conclusions are very scanty. I would extend this section keeping an eye on the
future
3) please revise the paper in terms of language before resubmission.
