With these methodological advances, it is expected that more realistic GD situations can be mimicked in future experimental phantom studies.
There are some methodological limitations: It is unclear whether and how allocation concealment and blinding of the outcome assessment were done in this study.
Their finding is very difficult especially from methodological aspect (it is given by a range, structure, representativeness and credibility of available data).
