Reviewer's report:  
 
This is a well -organized study investigating the effects of HDL/LDL ratio in predicting the 
mortality of acute pancreatitis patients. Here is some advice on this manuscript:  
 
 
Minor:  
 
1.in the conclusion part, our results suggest that lower H/L ratios are independently associated 
with poor progression in patients with AP, maybe here "lower H/L ratio" should be "higher H/L 
ratio"?  
 
2.in table 4, the column title "LDL -C&lt;0.465" should be  "H/L ratio &lt;0.465".  
 
 
Major revision:  
 
1.as discussed in previous researches, as well as according to our observation in the clinical 
practice, the change in cholesterol levels is often associated with or be companied by the change 
in triglyceride (TG) le vels, especially in HTG origin AP patients, so we think it makes sense to 
rule out the effects of HTG on clinical outcomes in AP patients, as it is reported that HTG was 
strongly and independently associated with the disease severity, and the occurrence of  organ 
failures in AP patients.  
 
2.When we talk about the early assessment of disease severity and clinical outcomes of AP 
patients, we do not think mortality is an indicator "early enough" for AP patients' stratification in 
the ICU, we recommend the author s focus more on the organ failure, especially the occurrence 
of persistent organ failure in AP patients and the predictive values of H/L ratio in it. Organ 
failure is the most important determinant for outcomes in AP patients and often takes place in the 
early stage.
