Reviewer’s  report:  
 
The authors have adequately addressed reviewer concerns.  A few minor errors should be 
corrected before publication.  
 
Line 104:  Do the authors mean that the height of the deductible is to some extent elective, rather 
than eligible?  
 
Line 334: Se ntence requires revision.  
 
Line 499: Should be "…slightly lower than that of a large…."  
 
Line 503: Should be prevalence rate rather than prevalence rates.  
 
Line 610:  Should read, "…women incurred higher total health care costs…" instead of 
"…women occurred…"
