Clinician expertise (CONSORT-NPT item 15)
Provision of information about clinician qualifications, grade, number
of AVBs previously undertaken (including those using the device under
evaluation) and total number of births annually in the unit, were
recorded. The number of clinicians undertaking AVBs in each trial group
was documented, including whether they performed AVBs within one or more
trial group. Information about study entry criteria for clinicians was
extracted (e.g. supervision, eligibility or completion of pre-study
training materials). Any descriptions or references to clinician
learning curves were extracted verbatim.
