GM prepared protocols and methods of the study, performed manuscript critical review and supervision of the study, and revised the draft manuscript.
Systematic reviews should be conducted according to a previously prepared protocol and based on studies with least potential of bias (Section 4.2.3, 5.2.2, 5.2.4 and 6.2.6 GMTA).
The study was conducted based on a prospectively prepared protocol, using the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.
We followed the PRISMA-P guideline for preferred reporting for systematic review and meta-analysis protocols in preparing this protocol.
In preparing this protocol a full systematic review and meta-analysis of previous work has been completed.
Adverse events and case reports found in the literature were reviewed when preparing the protocol [ 3, 35- 37].
Samples were prepared following protocols described previously [29 31].
The whole mounts were prepared following protocols described previously [ 16].
We suggest that simulation be used to prepare precise protocols for future serious events.
AB and LD prepared the protocol.
AE, PBF and BE prepared the protocol.
