Reviewer's report:  
 
Dear authors,  
 
you declare that you explained why 100 respondents and how were they selected. But you do not 
do this! You write "The study population included all males and females between 15 -49 years of 
age living in Effutu Municipality"; how big is this study populatio n in total? Is it 1000? or 
10000? or 15478? You shall provide the total number!  
 
Then you write "A multistage sampling technique was used to select respondents for the study." 
How exactly did you do the multistage samplig? Can you provide a flowchart for it  with numbers 
and inclusion/exclusion criteria described?  
 
Next you write "As per the estimated sample size calculated, a total of one hundred (100) 
respondents..."; how did you calculate the estimated sample size? Can you provide the formula, 
or the refere nce to the sample size calculation formula?  
 
This is a major issue to be able to assess validity of your findings; it needs to be described
