Title: Ultrasonographic scores for ileal Crohn’s disease assessment: better, worse or the same
as contrast-enhanced ultrasound?
Version: 2 Date: 24 Mar 2022
Reviewer's report:
The reviewer had asked if the ultrasound operator was blinded to the results of the
ileocolonoscopy. Altough the authors explained in their answers that the ultrasound operator
was not the same that performed ileocolonoscopy examinations and the ileocolonocopy
examinations were performed after ultrasonographic examinations by an operator without
experience in ultrasound, this does not necessarily mean that the investigators are blinded. The
authors should only use the expression “blinded”, when US operator and endoscopist haven´t had
access to the reports of the other investigator. The authors should clearly state this.  Otherwise,
they can´use the expression “blinded”.
