Reviewer's report:  
General  
1. This is a clearly reported and analysed manuscript describing the distribution and 
predictors of an important measure to protect against HIV in a vulnerable population in a low -
income country. Sufficient cultural context is provided for a n international audience. Findings 
are appropriately prioritised, interpreted, and placed into the context of the literature. I have one 
concern about the statistical approach. I believe the sampling procedure (p.3 ll 40 -59) described 
is proportional strat ification by health centre, and the summary statistics and measures of 
association do not appear to have been adjusted for stratum size.  
2. Introduction - It would be helpful, given the other recent reports from Ethiopia cited in 
the Discussion (reference s 4, 28, 30, 31, 34) to briefly describe the new and different information 
contained in this study. Gondar City has not previously been studied, but what does this study 
add to the knowledge gathered by considering other jurisdictions? If you can describe the 
knowledge gap, this will help the international audience of BMC Women's Health understand the 
significance and importance of this study.  
Specific  
1. Table 3. Although statistical software generates p -values reading "0.000" such values are 
rounding erro rs and as zero is the asymptote, these values should be described as " &lt;0.001" 
instead. As well, confidence intervals' upper and lower bounds should be expressed to the same 
precision, even if the last decimal place is zero.  
2. References - Journal info rmation is missing from reference 25
