Reviewer's report 
 Inhibition of the oxytocin receptors delays gastric emptying Title: 
 3  3 February 2006 Version: Date: 
 Ad A Masclee Reviewer: 
Reviewer's report: 
General 
The authors have responded in detail to the comments and questions. There remain concerns about 
the lack of data between 15 and 90 min.However, to obtain these data a new study has to be 
performed. I suggest to accept the paper,but 1) to include or refer to plasma oxy data of previous studies and 2) to specifically mention in the discussion that not the proces of gastric emptying but 
just gastric volume at two time points has been obtained. The individual data on GER are illustrative 
and show large variation.
