Reviewer’ s report
Title: Colonoscopy overuse in colorectal cancer screening and associated factors in Argentina: A
retrospective cohort study.
Version: 0Date: 04 Apr 2017
Reviewer: Cesare Hassan
Reviewer's report:
The AU assessed the rate of inappropriate colonoscopy, also linking such estimate with the
previous diagnosis to HP. The main criticism is that we are not aware whether the US GLs that theAU used as gold-standard had actually been disseminated among PCP and endoscopists. Can theAU provide further info on this aspect? If such GLs were not distributed at the time ofprescription, the study remains interesting, but it represents what can be gained by theimplementation of such GLs.
