PEER REVIEWER COMMENTS:  
 
GENERAL COMMENTS: I have reviewed the author responses line -by-line and corresponding 
sections of the manuscript.  Overall the authors have satisfact orily addressed key concerns raised 
in the first round of peer review, with particular focus on study population, covariates, and 
outcome definitions in the methods section, and implications of the study findings.  In the end 
there are intrinsic limitation s of this retrospective cohort analysis due to missing data (non -
modifiable), but the authors have appropriately cited these limitations in the discussion section.  I 
would accept the revised copy of this manuscript.
