Title: Texture and color enhancement imaging improves the visibility of gastric neoplasms:
Clinical trial with image catalogue assessment using conventional and newly developed
endoscopes
Version: 2 Date: 27 Jul 2023
Reviewer's report:
The authors showed that TXI, a new Image enhanced endoscopy, improves the visibility scale
of gastric neoplasms compared to WLI. Although several reports similar to those of the authors
have already been published, it is worthwhile to calculate the sample size and to study it in
consecutive cases. However, I have several concerns.
My comments are as follows:
#. It is worthwhile to enroll consecutive cases. It is noted in the discussion section, but should
be noted in the methods section.
#. The possibility that a new method bias may exist based solely on the endoscopist's judgment
of visibility cannot be ruled out. This should be mentioned in the limitation.
#. Table 2: The authors use analysis of variance in their statistics, but the data they examined do
not seem to be normally distributed. The authors should confirm whether the statistical method
is appropriate or not.
#. The following papers have conducted similar studies and should be referenced.
