Reviewer’s report
Title: A population-based cohort study of mortality of intensive care unit patients with liver
cirrhosis
Version: 0 Date: 30 Aug 2019
Reviewer: Michel Scotte
Reviewer's report:
This is a nice paper that shows that liver cirrhosis was associated with increased mortality in ICU
patients. Furthermore, one-year mortality was also higher in this group of patients. Some points have to
be addressed:
1. Could the authors discuss the methods since control group was strictly similar to cirrhosis
group, that is quite surprising…
2. Was the diagnosis of cirrhosis really validated? Could some patients with hepatitis without
cirrhosis be included in cirrhotic group?
3. In patients hospitalized in ICU, I think that biological parameters can be obtained in registers.
So, was there a difference in mortality rates according to Child-Pugh status, or MELD score? 
4. Could the authors provide an actuarial survival starting at the day of ICU admission?
5. What kind of specific protocol can be applied to improve the management of cirrhotic
patients??? Will the result of these series modify the rate of ICU  admission in end-stage
cirrhotic disease, such as patients with C child's score?
Are the methods appropriate and well described?
