Reviewer's report:
Thanks for giving me the chance to review this clinically important article,
however i have some concerns
1) the sample size may be small to draw a conclusion in this epidemiologic
study. Please provide the rationale behind using this sample size; SS calculation. 
2) If the authors use stat graphs, this would be meaningful. 
3) The authors should provide a plausible explanation for their findings to enrich
the discussion section. ?? genetic background, ??similarity to another race is the
same PCOS distribution.
