Reviewer's report:  
 
Thank you for sending me thi s article for review.  
As a whole I would rank this article above average.  
It is addressing and important aspect of the women health "PMS"  
 
I have a few comments:  
ABSTRACT: Abstract is well written, but in the results section the  word significant is used 
twice.  
 
INTRODUCTION: Introduction is fine, Line 20 (please rearrange the sentence)  
Reference 3 11 is not needed, as it is not relevant to the study.  
 
METHODS: Methods section is well written, but please write the exclusion criteria clearly. I can 
see non acceptance in the study and the exclusion criteria/ both are overlapping. no need to 
mention them separately. Unite them together to show a clear cut exclusion criteria.  
 
RESULTS: The results need improvement. First of all provide the foot notes for the tables. each 
table should be self explanatory. Mention the P values clearly and also the significant p values 
should be highlighted by *sign. I prefer that p valu es should be  mentioned as < or> 0.05 
according to their significance.  
 
Word swollen have been used in the symptoms , I can not understand it. Plz mention clearly that 
either it is swelling? If yes than swelling of which part? either abdominal swelling. or  
generalized body swelling?  
Heart rate have also been mentioned in the symptoms, also mention clearly  Increase in  heart 
rate?  
 
DISCUSSION:  Discussion is very poorly written. I recommend that the discussion should be 
rewritten.  
Needs a lots of rearrangemen t/ removal of unnecessary information/ removal of overlapping and 
repeating stuff.  
 
Discussion should be arranged as below:  
Arrange the paragraphs in such a way that each significant finding should be mentioned first, 
than the studies in favor and opposing  it should be mentioned. But it must be very organized. 
You should go step wise, first for the symptom which is mentioned first in the table  and than so 
on. plz avoid to be haphazard.  
Unnecessary explanation of the symptoms is not needed in discussion, as  most of the 
mechanisms have already been discussed in the introduction section.  
The last paragraph of discussion was really not needed.  
 
Limitation and strengths of the study  should be mentioned in the last part of discussion.  
Closing of discussion sho uld show proper conclusion and future recommendations.
