Reviewer's report:  
It's a study aimed to measure the prevalence of breast disorders in a group of pregnant women.  
The goal of the study is cle arly defined.  
However it is not clear how the study can be defined as longitudinal study.  
 
1248 pregnant women were recruited in their first trimester till 26 weeks gestational age 
consecutively in Ibadan, Southwest Nigeria.  
Clinical Breast Examination usi ng MammaCare technique was performed at recruitment and 
subsequent visits, six weeks postpartum and six months postpartum. Women with breast 
disorders were referred for Breast Ultrasound Scan and finally 3 women had ultrasound guided 
biopsy.  
This study sho wed poor compliance at follow -up. 
 
Two suggestions:  
1. To reconfigure the study as a prevalence study of breast disorders in pregnant women.  
2. To draw up a table comparing the main characteristics of women with and without breast 
injury.
