Reviewer’s report
Title: Prognostic factors of acute mesenteric ischemia in ICU patients
Version: 1 Date: 13 Sep 2018
Reviewer: Stefan Acosta
Reviewer's report:
The Odds ratios with 95% CI and p values for your three main findings are identical in the previous  
manuscript draft and revision 1. Please recalculate after omitting the mesenteric venous thrombosis  
patients and redo in Abstract-Results + Results + Table 3
For a broader readership to get a grip of this material it is essential that the primary diagnosis are stated,  
at least in Table 1 and Table 2. I understand that this is not your primary area of interest but it is very  
important for surgeons. Can you perform subgroups? Primary arterial AMI/ischemic complications to  
aortic aneurysm repair/ileus/miscellaneous (at least these four subgroups) and then it would be possible  
to state p values in Table 2.
Are the methods appropriate and well described?
If not, please specify what is required in your comments to the authors.
