Reviewer’s report
Title: 
Does Sequential Balloon Expulsion Test improve the screening of
Defecation Disorders?
Version: 
0 
Date: 
10 Jul 2020
Reviewer's report:
It seems a bit strange that clinical score displayed such a low specificity; tha
same can be told about the low sensitivity of digital rectal examination; it may be
because of some grade of dissinergy present even in NoDD pts? moreover, as
stated by the authors, DRE is an operator depending technique as in some
aspects even the clinical scores (individual capacity of interviewing the pts).
