Reviewer's report:  
 
1. The manuscript requires thorough language editing.  
 
 
2. The objective of the stud y could be focused only on the prevalence of dysmenorrhea and 
its concomitants. The management part is not required in the context of the manuscript.  
 
 
3. The method section does not allow a reader to understand the data types collected, the 
description of t he variables used in the study, the age range of the participants, the 
statistical analyses undertaken in the study. This part requires serious revision.  
 
 
4. The discussion section lacks the critical appraisal of the result. It failed to address the 
why so ciodemographic variables and other menstrual characteristics showed significant 
association with dysmenorrhea.  
 
 
5. The author can take up a binary regression analyses in order to understand the 
determinants of dysmenorrhea in the study population.
