Reviewer’s report:  
 
It is very interesting, well developed and with clear conclusions.  
 
 
My comments are:  
 
- I do not understand why the Hispanic female population is so low in the study, when in the 
United States alone, the Hispanic population is 11.7% of the entire population.  
 
- The clear criticism of the study is that it compares a population of 260 versus 3.616, as th ey 
point out.
