Reviewer's report:
Thanks for doing my comments. Some more corrections are need.
Title:
Kindly change the type of study to "a Semi-experimental study" 
Abstract:
- The abstract is too long, kindly omit these sentences:
"of participants including duration and interval of menstrual cycle and the
amount of pain relievers consumed during menstrual pain" (line 29-31).
" In all 140 female students (70 per each group) were entered into the study."
(line 41)
- Write descriptive statistics such as mean, standard deviation and frequency.
- Report the frequency of students for this part "The number of students who had
normal duration" (line 43).
- Report p values for "significant declines in menstrual pain" (line 51) and
"significant declines in menstrual pain" (line 56).
Method:
- According to the aim of this study it seems the primary out come was severity
of pain and the secondary outcomes were duration of menstrual bleeding,
interval of mensuration cycle and the number of pain killer…
- Frequency and percentage is the same, delete percentage (p.9, line 58)
- In addition to chi-square, t test was use for comparison of quantitative
demographic characteristics. (p. 10, line 4)
- kindly report by which test "some values normality was not confirmed" (p.10,
line 9).
Results:
- Change this sub-title "Study samples" to "characteristics of participants"
- Age was reported in table 1, so delete this sentence "The mean (SD) age was
21.6 ± 2.31 and 22.4 ± 3.02 years in water intake and control groups,
respectively". (p. 10, line 29).
- In the "Menstruation interval" and "Pain killer" sections please omit the
frequencies that were reported in the tables. (p.11)
Table1:
- Complete the title as: demographic and menstrual characteristic of female
students who suffered from primary dysmenorrhea in the water intake and
control groups.
- Add "number (%) for faculty variable
- Just report the name of test and delete "Derived from". Do this comment for all
tables.
Flowchart:
