Effects of a dietary modification intervention on menstrual pain and urinary BPA
levels: A single group clinical trial 
Thank you for inviting me to review this manuscript. Please see my comments
as follow:
1. Background should start with the problem. In this study the problem is
dysmenorrhea and pain and should be introduced first. 
2. The adherence to dietary modification should come prior to pain and urinary
BPA. 
Method
1. There is need more information about the field of study of participants. If
students had field of study related to medicine, then they should know what
effective factors on dysmenorrhea are. 
2. Who conducted the educational classes? Was he/she blinded to purpose of
study?
3. This was not a randomized controlled trial, therefore registering in RCT
registry and following CONSORT guidelines was not necessary.
4. Why the number of students in each small group was not distributed equally
(10 women in each group).
5. Please provide more information about social networking communication.
Was 30 students in one social networking group?
6. How the researchers ensured about all participants had primary
dysmenorrhea?
Discussion
1. Please mention the purpose of the study at the beginning of the discussion. 
2. Please state the main results of the study after stating the objectives of the
study.
