PEER REVIEWER COMMENTS:  
 
GENERAL COMMENTS: Overall, the introduction, and study objectives are clear. However, 
the sample sizes are small, only 31. Several measures of subjects had large variations.  
 
REQUESTED REVISIONS:  
Major reversion is needed (see Summary Comments).  
ADDITIONAL REQUESTS/SUGGESTIONS:  
Some interpretations are confused or misleading.  Such as this sentence: "In our study, patients 
with acute abdominal trauma were younger than patients with ANP; however, thi s difference was 
statistically insignificant (P=0.051)."
