Reviewer's report:  
 
I read the article with interest. The study entitled "Relationship between sleep quality and 
cardiovascular dise ase risk in Chinese post -menopausal women" examines the relationship 
between sleep quality and risks for cardiovascular diseases (CVD) among Chinese post -
menopausal women.  
 
It would be better to have two groups (age and BMI -matched post -menopausal women wi th good 
and bad sleep quality) and to compare them in terms of cardiovascular disease risk.
