Data Extraction:
Data from all included studies was extracted independently by two
researchers (BR and SM) into a datasheet compiled for this review.
Extracted data included information related to the setting, study sample
size, the type of huddle specified, methods of evaluation, the
intervention content and duration, main findings or emergent themes,
general conclusions, and limitations of the studies. Reviewers also
collected information such as first author, publication year, and study
design. All reviewer conflicts were resolved by a third researcher (SA).
