Reviewer's report:
The authors in this manuscript developed and validated machine learning (ML)
models to predict 28-day mortality for patients with HE.
The idea is good, the work achieved the aim of the study, but the manuscript is
written by non-native English and needs major language revision regarding
grammar and punctuation.
These are few comments to be regarded:
Abstract:
Page 2; line 55: "ratio of 3:7" should be changed to "ratio of 7:3"
Page 3; line 25-27: "Sodium for End-Stage Liver Disease" should be changed to
"Model for End-Stage Liver Disease-Sodium".
Introduction:
Language editing should be reviewed e.g. "However, many existing" in page 4;
line 15 is better to start with "Many existing…"
Page 4; line 23: "Sodium for End-Stage Liver Disease (MELD-Na) model"
should be changed to "Model for End-Stage Liver Disease-Sodium (MELD-Na)"
here and anywhere in the manuscript.
Results: 
Page 7; line 24: "survivals" should be changed to "survivors".
Discussion:
Language editing should be reviewed e.g. "And mechanical ventilation" in page
9; line 59. It is better to start with "Mechanical ventilation…"
Page 10; line 25-29: "This study had several.." needs revision and rewriting in a
better language.
Page 10; line 31: "Moreover, this study..". It is better to start by "This study…"
