Reviewer's report:  
 
Reviewer #1 comments to manuscript number BMWH -D-16-00043R2: 3 -dimensional versus 
conventional laparoscopy for benign hysterectomy: protocol for a ran domized clinical trial  
 
 
 
I find that the authors have carefully complied with my previously raised concerns in BMWH -D-
16-00043R1. However, in the revised Table 1 no information is given concerning the baseline 
QoL assessment. This should be added in the description of the baseline  variables in the table. 
After this minor adjustment I will recommend the manuscript acceptable for publication.
