Reviewer 2 Report
congratulations to the authors for the well-written article. Please answer the following comments.
- There are only 4 articles eligible for the meta-analysis, which is a very limited number of articles to come to a conclusion about the efficiency of effectiveness, and safety of botulinum 19n toxin type A (BoNT-A) injection in cerebral palsy.
- can you please explain in detail the 3 types of BoNT-A?
- Does onabotulinumtoxinA FDA approve for treating sialorrhea in children with Cerebral palsy? is it an off-label use?
- Please comment about rimabotulinumtoxinB use in sialorrhea in CP children and is it FDA approved? Also please cite any article if available.
- The reference article 21 stated major complications in 5 patients who were hospitalized after BoNT-A injection. Can the authors explain how they came to a conclusion the use of BoNT-A is safe with very few side effects?
