Reviewer's report:
"REVISION ASSESSMENT FROM THE ACADEMIC PEER REVIEWER: 
Has  the  author  addressed  your  concerns  sufficiently for  you  to  now  recommend  the  work  as  a
technically sound contribution? Yes
Reviewer comments: THE MANUSCRIPT READS BETTER AND IS MORE SCIENTIFICALLY
CORRECT-- WELL DONE  AUTHORS!  BUT THERE ARE STILL SEVERAL POINTS  THAT
WOULD BENEFIT BY CHANGING- SEE BELOW. 
1. Make your conclusions in the abstract stronger by saying that AIMS65 is a much  easier,  readily
calculated  scoring system compared to the others maybe by ending the conclusions with", but the
AIMS65 scoring system is much easier and readily calculated that the other scoring systems"
2. Add the statistical comparison of the AIMS65 to the other scoring systems in the legend to figure 2
3. Table 4 what are the p values comparing. Best to add a footnote describing this
3. Page 5 line 11 I personally would change the term "spurting" to "actively bleeding"
4. I really think that you should address the limitation of total patient number in the limitations section
of the discussion one sentence only
5. Page 12 lines 33- 39  you need to reword this to" Our study strongly suggests  that the AIMS65
scoring system is better than the GBS system for predicting mortality (p=0.07) ". This way the reader
can determine if they think it is superior ( remember your numbers are not great enough to really
answer the question statistically and the p value is NOT truly statistically significant. Be upfront  and
word it as "strongly suggests" rather than claiming it IS superior."
