randomized clinical trial

Reviewer's report:  
 
Nice trial. However there are some language failures and some points that in my opinion are 
limitations of the trial.  
 
To collect information only by teleph one seems to be very weak! Why not asking for a 
questionnaire to fill in the complications and back to work information.  
 
Should be nice to incorporate an economic analysis
