Dear Authors,  
 
It is a really interesting and well -written article on an important topic, and still under -reported on 
the Literature.  
 
 
Nevertheless I have some questions and suggestions:  
 
- What is the meaning of a MPR of 1.05?  
 
- Did you find any association between a low MPR and some characteristics of the patients or the 
prescribed antiviral? It would be interesting to know.  
 
- Can you compare your study to the others similar to yours? (besides the fact that your is the 
biggest one)

If not, please specify what is required in your comments to the authors.
