Title:Liver disease and 30-day mortality after colorectal cancer surgery: A
Danish population-based cohort study
Version: 2Date:12 February 2013
Reviewer: marco montorsi
Reviewer's report:
Discretionary revisions
Due to the long period of the study, it may be of interest to know if AA found any
difference in mortality when the study period is divided in two or more years
range .
Are there more specific information about the causes of death both overall and in
the different study groups ( no liver disease vs other groups ) ?
Because mortality may be related also to hospital surgical volume and specific
experience , do the AA can retrieve data about this association ( do high-quality
or referral hospitals have lower risk of operative mortality for those high-risk
patients ?).
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Acceptable
Statistical review: No, the manuscript does not need to be seen by a
statistician.
