Reviewer's report:
Thank you for your efforts in revising the manuscript. Although many issues are
solved during the revision process, their still remain some critical issues to be
pointed out.
[Major]
#1. The conclusion still needs to be revised further.
The authors replied: "Yes, the result of this study cannot be applied to all
patients."
-> Then, I recommend the authors to revise the manuscript accordingly. Add this
point as a limitation in discussion section, and tone down the conclusion (avoid
using the expression "antibiotics should not be used") with mentioning that this
study's results cannot be uniformly applied to all the patients regardless of their
clinical situation (or can be applied to patients without serious co-morbidities).
[Minor]
#1. There are many typos and errors in grammar and expression of units
throughout the manuscript, which need to be corrected.
