Reviewer's report:
Dear the Editor,
I have reviewed the manuscript  ID 30c5977c-6923-4679-85c3-92d60b14a940 entitled “High-
Dose Polyethylene Glycol-3350 and Gatorade Solutions for Patients with Previous Inadequate
Bowel Preparations for Colonoscopy are Safe Effective”. However, there are some major
concerns as the following;
Major concerns
1. This manuscript was redundant and difficult to follow. For example, the authors should
explain the definition of step 1 and step 2 again in the manuscript and give more detail when
they initiated step 2 in the manuscript, not only put them in the abstract, etc. The manuscript
should be rewritten.
2. It was unclear that why the authors had to use the historical controls in this study as the
quality of bowel preparation has its cut-point number to categorize to poor, good or excellent
preparation.
3. The result part should contain the content of result in the text as well, not only refer the
information to the tables.
4. As there were a lot of digits in this manuscript, especially in the discussion part. The author
should provide the most simplify data to the reader.
