Title:Variable-stiffness colonoscope makes colonoscope easier?A
meta-analysis of the efficacy compared variable stiffness colonoscope with
standard adult colonoscope
Version: 4Date:30 April 2012
Reviewer: Praveen Roy
Reviewer's report:
Overall a well done meta-analysis.
Minor
There are few spelling errors that need to be corrected (eg word ' Studie")
Major
In the conclusion the authors report a higher cecal intubation rate ( RR 1.03).
They should explain how this translates clinically in clincal practice. This is
clinically meaningful finding.
Author indicate they did a sentivity analysis to explore heterogenity. They need to
expand on this and explain what they found and how they can explain the
heterogenity.
Level of interest: An article of importance in its field
Quality of written English: Acceptable
Statistical review: No, the manuscript does not need to be seen by a
statistician.
