Reviewer's report:
This article aimed to investigate whether plasma soluble urokinase plasminogen
activator receptor (suPAR) is a suitable biomarker for the prognosis of patients
with ACLF.
The subject is worthy of investigation, and existing data is scarce.
The study has been well conducted.
Results have been nicely presented.
Discussion is appropriate.
Few minor comments
1. suPAR full for should be mentioned when this abbreviation is first used in
Introduction line no. 83.
2.Table 1- Labels (A), (B), (C) and (D) should be deleted in the heading row.
