Round 1
Reviewer 1 Report
The article is very interesting on the subject and is well structured and has a well organized progression. The figures are accurate. I would say that a tab is needed on the discussion with the risk factors found in comparison of the countries studied.

Reviewer 2 Report
1. Could the author interpret the data? Why and how China, Brazil, and India have an inspiring decline in ASMR of PUD.
2. The inclusion and exclusion criteria are not clear.
3. The discussion section is poor. The author has to explain the previous study and discuss that.
4. I suggest the author make a table and describe the results.
5. What is the home message of the study.
6. What is the future study.

Reviewer 4 Report
Existing papers have evaluated the incidence of PUD in various countries. It is not clear why this study was conducted in India, Brazil, and China.
A further result of this study is that they focused on Smoking and added more assessments.
However, the relationship between smoking and PUDs, which is the subject of this paper, has been pointed out in the past.
A more detailed evaluation of smoking and eradication seems necessary.

Reviewer 4 Report
In your paper's concluding paragraph, isn't it an overstatement to say that smoking policies reduced PUD?
