Reviewer's report
Title:Narrow-band imaging does not improve detection of colorectal polyps
when compared to conventional colonoscopy: a randomized controlled trial and
meta-analysis of published studies.
Version: 5Date:9 September 2011
Reviewer: Toshifumi Hibi
Reviewer's report:
(Major)
Although some studies have shown an improvement in the adenoma detection
rate with NBI compared with conventional colonoscopy, there have been studies
in which the benefits of either technique were not statistically significant in
detection rates between the two groups. The authors’ RCT does neither add
much new evidences nor originality to our present knowledge, and their data,
including the figure shown in Table 3, is confusing, as reviewer2 pointed. But
their meta-analysis has some clinical importance and reviewer2 does not seem
to have any objection for it. Additionally, the authors have almost responded to
the major compulsory revisions given by two reviewers. I think the latter portion
of their paper(meta-analysis) is , at least, acceptable.
(Minor)
The total examination time (about 9 min) seems to be too short.
